The FN P90 submachine gun (SMG) was developed in the late 1980s as a personal defense weapon for the troops whose primary activities does not include small arms, such as vehicle and tank crew members, artillery crews etc. Standard pistols and submachine guns chambered for pistol rounds were proved ineffective against enemy soldiers, wearing body armor; Therefore FN designers first developed a new round with enhanced penetration, initially known as SS90. To achieve necessary high penetration while keeping recoil impulse low, FN used a small-bore approach, creating a round that looked much like the scaled down 5,56NATO round. It must be noted that similar concepts were tried in other countries, most notably in USA, several decades before FN; for example, US Army tested M1 carbines chambered for .221 Johnson Spitfire round back in late 1950s; later on, Colt produced its .22 SCAMP and 5,6x30 MARS ammunition for special SCAMP machine pistol and MARS "mini assault rifle" (a scaled-down M16 rifle) respectively. It must be noted that 5,6x30 MARS round was in a sense a direct predecessor to 5,7x28 FN SS90 round, although the latter featured slightly lighter and faster bullet. By late 1980s a concept of a small-bore, low-impulse "personal defense weapon" (PDW) with good accuracy and lethality at ranges of up to 200-250 meters was well established, although there were no weapons adopted for service yet. FN decided to follow this concept and to create its own PDW using clean sheet approach. Basic ideas used for this development, designated as "Project 9.0", included the following: minimal size and weight of weapon; large magazine capacity; complete ambidexterity; ease of use and maintenance.
To save on size and weight, FN designers put new weapon into compact and lightweight stock of bullpup layout, made of impact-resistant polymer. The high-capacity magazine also was made from semi-translucent polymer, and holds 50 rounds in two rows. To made loaded weapon as compact as possible, FN designers followed the idea of American designer Hall, and placed the magazine above the barrels, with cartridges stored in horizontal position with bullets pointing to the left. While Hall system employed a rotary feed unit, operated by the bolt, to put new cartridge in line with the barrel, FN designers incorporated a stationary helical ramp into each magazine, which rotates cartridge for 90 degrees prior to placing it into feed lips. Complete ambidexterity was achieved by using ambidextrous controls (including dual charging handles and dual back-up open sights), and bottom ejection. Finally, simplicity of aiming was achieved by use of integral reflex type collimating sight and integral laser aiming module (LAM).
Resulting weapon appeared in around 1990 as FN P90 personal defense weapon, along with improved 5,7x28 SS190 ammunition, which replaced polymer-cored bullets with heavier dual-core (steel / aluminum) bullets with better penetration against body armor. Several other types of ammunition were developed for this weapon, including tracer, subsonic ball and soft-core training ball.
First sales of P90 were made to Saudi Arabia in early 1990s; today it is believed that FN sold more than 20 000 of P90's to a wide variety of law enforcement agencies and military special operation units worldwide, including US Secret Service, Austrian Army rangers, Dutch BBE special operations forces, Belgian Army and others. Most interesting fact about adoption of P90 is that so far it has been adopted for the role, directly opposite to its original niche of "personal defense weapon". In fact, most services and agencies that adopted P90 use it for offensive roles, as a specialist or even a primary weapon for various assault teams, and other "professional small-arms users", as opposed to military personnel which primary functions do not include use of small arms.
In around 1995 FN supplemented the P90 with pistol, firing the same 5,7x28 ammunition, designated as FN Five-seveN. Recently, FN also introduced a civilian version of P90, designated as PS90 carbine. This is a self-loading weapon with longer barrel (408 mm / 16").
FN P90 personal defense weapon is blowback operated, selective-fired weapon which fires from closed bolt. The firing is controlled by a removable trigger unit with conventional hammer. A manual safety is located directly below the trigger. Magazine lies at the top of the weapon, feeding from front-to-back, with spiral ramp built into the "rear" part of the magazine. Spent cartridges are ejected straight down through the chute, which exits just behind the pistol grip. The standard sighting equipment includes a non-magnifying collimating sight with "ring and dot" illuminated aiming reticule. Back-up open sights are provided at either side of the primary collimating sight. The so-called P90 USG version is provided with two additional Picatinny rails at either side of the collimating sight base; FN also offers a version with no standard sighting equipment; user has to make its own choice of day and/or night sights and additional equipment, which can be installed on three Picatinny rails - top, left and right. This version is designated as P90 TR (triple rail). The front part of the forward handgrip on P90 is shaped as hand protector, and it can contain integral laser aiming module, which sends either visible or IR laser beam to mark the intended target. For special missions P90 can be fitted with a special silencer, which is used in conjunction with special subsonic ammunition.

The development of the XM8 Lightweight Assault Rifle was initiated by US Army in the 2002, when contract was issued to the Alliant Techsystems Co of USA to study possibilities of development of kinetic energy part of theXM29 OICW weapon into separate lightweight assault rifle, which could, in the case of success, replace the aging M16A2 rifles and M4A1 carbines in US military service. XM8 is being developed by the Heckler-Koch USA, a subsidiary of famous German Heckler-Koch company. According to the present plans, the XM8 should enter full production circa 2005, if not earlier, several years before the XM29 OICW. The XM8 (M8 after its official adoption) should become a standard next generation US forces assault rifle. It will fire all standard 5.56mm NATO ammunition, and, to further decrease the load on the future infantrymen, a new type of 5.56mm ammunition is now being developed. This new ammunition will have composite cases, with brass bases and polymer walls, which will reduce weight of the complete ammunition, while maintaining compatibility with all 5.56mm NATO weapons. Along with 20% weight reduction in the XM8 (compared to the current issue M4A1carbine), this will be a welcome move for any infantryman, already overloaded by protective, communications and other battle equipment.
The XM8 will be almost similar to the "KE" (kinetic energy) part of the XM29 OICW system, being different mostly in having a telescoped plastic buttstock of adjustable length, and a detachable carrying handle with the sight rail.
As of mid-2004, XM8 now is undergoing wide-scale testing in several units of US Army, and is receiving a positive feedback.
XM8 status update (September 2005): Following several complains about non-competitive procurement of the XM8 system from Heckler-Koch USA, US Army first opened the bidding for contract to other companies, and then, in the July 2005, suddenly suspended the entire OICW Increment 1 program to re-think the entire set of requirements for the possible replacement of current M16 rifles and M4 carbines. These requirements will be re-viewed as Joint Services effort. At the present time, it seems that development of HK XM8 is suspended; it may be resumed if XM8 suit the new US Joint Service Requirements for a new assault rifle system; or, it may not. We will watch this process closely and update this article when new information will be available.
Technical description.
The XM8 is a derivative of the Heckler-Koch G36 assault rifle, and thus it is almost similar to that rifle in design and functioning. XM8 features a short piston stroke, gas operated action, with rotating bolt locking. Barrels are quick detachable, and planned to be available in several sizes, ranging from 229 mm (9.5 inch) for Compact/PDW version, 318mm (12.5 inch) in Basic version, and two 508mm (20in) barrels, one for Sharpshooter/Sniper version, and heavier one (along with bipod) for Squad Automatic Rifle role. The entire construction is modular and built around the polymer receiver with bolt group; Magazine housings could be easily swapped for compatibility with various types of magazines; various buttstocks could be installed in a second for various roles (standard buttstock is a telescoped 5 position adjustable one). Top of the receiver is fitted with proprietary sight rail, which can accept illuminated red-dot (collimator) sight, or any other type of sighting equipment. Detachable forend will be available in various sizes, and could be replaced with XM320 40mm grenade launcher (the improved HK AG36).

The AICW (Advanced Infantry Combat Weapon) is a joint development of the Australian DSTO (Government operated Defence Science and Technology Organisation), and private companies Metal Storm and Tenix Defence. This development has been carried out since the turn of 21st century, closely following the concept of the American XM29 OICW system. Overall, AICW represents the modular weapon system that combines the 5.56mm rifle/carbine copmponent as a host (basic) platform with 40mm multi-shot grenade launcher (G/L) module and multi-purpose electro-optical sighting system, which can be used to fire either rifle or G/L component, and also can provide recon data to external "consumers" such as tactical computers.
The host rifle component of the AICW is the updated Australian-made F88 rifle, which is a license-built Steyr AUG. However, the basic F88 rifle has been extensively modified to accept other elements of the system - for example, receiver has been upgraded to receive the G/L module at the top, and the buttstock has been enlarged to accomodate G/L electronic fire contol module. Other changes include modification to the safety and trigger arrangements - AICW system has a single trigger for both weapon components (5.56 and 40mm), and a three position (safe - rifle - G/L) safety/selector switch at the side of the pistol grip.
The most interesting part of the AICW weapon is the multi-shot Metal Storm 40mm grenade launcher, which looks like a single 40mm G/L barrel but contains three 40mm projectiles stacked one behind the another. These projectiles are launched using the electric ignition impulses, provided by the fire control module built into the buttstock of the host rifle. Since the muzzle velocity of these projectiles is slightly more than usual for 40mm handheld G/L (95m/s instead of 75m/s), host rifle incorporates the recoil reduction buffer, that allows the Metal Storm G/L barrel to recoil against the spring, decreasing the peak recoil impulse.
The top of the receiver hosts the multi-role sights of various type and make. At the AICW VX3 live fire demonstartions that took place in the summer of 2005, AICW prototypes were displayed with ITL Viper multi-purpose rifle sight (that incorporates laser range-finder and digital compas), or with Vinghog Vingsight Fire Control System. At the present time (late 2005) AICW prototypes have not yet fired 40mm grenades with live warheads, nor incorporated an airburst facility. However, it is stated that it is possible to easily adapt most of the existing 40mm grenade warheads to the Metal Storm technology, including air-bursting grenades that are now in development in several countries.

At the present time AICW weapons are available only as the "3rd generation technology demonstartors", that completed first live-fire trials (as a complete system) in the summer of 2005. Current Australian MOD plans state that ADF may start to purchase AICW systems in around 2010-2012.

The origins of the XM307 Advanced Crew Served Weapon (ACSW), also known as XM307 25mm Airbursting Weapon System, lie in the several military documents, published in USA during late 1980s. These documents stated that current small arms have reached its peak in development, and the only currently possible way to increase combat effectiveness and single-shot lethality of such weapons is do develop new guns that will fire air-bursting munitions with programmable fuses. Following these conclusions, US Army initiated development of several so-called Objective weapons; two most famous of these were XM29 Objective Individual Combat Weapon (OICW) and XM307 Objective Crew-Served Weapon (OCSW), currently renamed to Advanced Crew-Served Weapon (ACSW). After much development, the prime contractor for ACSW program was selected as General Dynamics Armament and Technical Products (GDATP). The development team for ACSW also includes General Dynamics Ordnance and Tactical Systems (air-bursting ammunition), Kaman Dayron Inc (programmable fuze) and Raytheon (computerized fire control system). First demonstrated in around 1999 as 25mm OCSW, at the present time (early 2006) the XM307 ACSW is on advanced stages of development, with several prototypes already tested with live ammunition, including air-bursting rounds. Initial plans called for first US Army units to be equipped with 25mm M307 ACSW weapons by 2008; M307 shall replace in service the older weapons like Mk.19 Mod.3 40mm grenade launchers and .50 caliber M2HB machine guns. For added versatility, XM307 can be easily converted to fire .50 caliber machinegun ammunition (12.7x99) with replacement of just 5 parts.
The key to greatly increased combat effectiveness of ACSW system is programmable air-bursting ammunition, which will be used in conjunction with electronic fire control unit. This ammunition will allow to precisely engage enemy personnel in open or in defilade, without the need for direct impact in the target area. Other types of ammunition proposed for XM307 ACSW are HEAT (with required armor penetration up to 5cm / 2in), less-lethal (with tear gas for peace-keeping applications) and training rounds with dummy warheads.
It is obvious that by the year 2008 the XM307 will enter into strong competition with several 40mm air-bursting weapons such as Mk.47 Striker 40, and the outcome of this competition is hardly predictable, as either system has its own merits and downsizes. ACSW is certainly lighter, fires lighter ammunition (allowing to carry more ammo in the same weight), and has longer range. 40mm weapons fire bigger warheads and can use huge stocks of already existing and well developed NATO-standard ammunition of various types, including point-detonating FRAG, HEDP, AP, less-lethal and many others.

XM307 Advanced Crew Served Weapon is gas operated, rotating bolt locked weapon that uses differential recoil system for decreased peak recoil. XM307 is belt fed weapon that fires from open bolt. The differential recoil system means that barrel and bolt group are allowed to recoil within the receiver casing together, against the recoil springs. When weapon is cocked for first shot, bolt is locked open and the entire barrel/bolt group is carried rearwards and also locked there. Upon the pull of the trigger both barrel group and the bolt inside it are released, and the bolt loads the round and locks it in chamber while barrel still moves forward; firing pin is then released immediately, and the recoil from the discharge first has to arrest the forward movement of the barrel group, and then throws it backward with less force than it would in the traditional system with fixed barrel. The belt feed and bolt cycling are operated by conventional gas action. The fire control unit includes zoomable day and night vision channels that output the sight picture to the small display at the rear of the sight. Integral laser range-finder allows for precise range measurement, necessary for automatic point of aim correction and for programming of the air-bursting fuzes. XM307 weapon is fitted with dual, ergonomically shaped spade grips with triggers and fire and sight control buttons. Additional buttons are located at the rear of the sight / fire control unit, below the eyepiece. In standard applications, XM307 can be used either on lightweight infantry tripod, or on vehicle mounts, manually or remotely controlled. For vehicular applications, GDATP will develop the dual feed option, which will allow to select the type of ammunition (anti-personnel HEAB or armour-piercing) at the instant before firing.

Steyr AMR / IWS 2000 (Austria)
Caliber(s): 15.2mm Steyr APFSDS
Operation: long recoil, semi-automatic
Barrel: 1200 mm
Weight: 18 kg
Length: 1800 mm
Feed Mechanism: 5 rounds detachable box mag.
The development of this interesting weapon began in mid-1980s, when Austrian company Steyr-Mannlicher AG decided to develop a long-range anti-materiel rifle (AMR) - a modern equivalent of the WW2-era antitank rifles. Main targets for AMR are light armoured vehicles, helicopters, installations such as radar cabins, missile launchers, fuel tanks etc. To achieve desired effective range of at least 1000 meters, Steyr engineers first decided to use APDS (armour piercing, discarding sabot), or sub-caliber, ammunition. Development started from 12.7mm cartridges, and later Steyr developed a 14.5mm APFSDS (Arnour percing, fin stabilised, discarding sabot) ammunition in 14.5mm caliber and built few prototypes with smooth bores and semi-automatic actions, called Steyr AMR 5075. Further development led to even bigger caliber of 15.2mm fith same ultra-high velocity APFSDS projectiles. This system is called Steyr IWS 2000 (Infantry Weapon System 2000) and currently is probably in Adsvanced Development status or ready for adoption.
IWS 2000 is wery formidable weapon. It fires 20 gramm (308 grains) tungsten dart (fleschette) with muzzle velocity of 1450 meters per second (4750 fps). At 1000 meters this projectile will penetrate a 40 mm of RHA (rollded homogenous steel armour) and will result in serious secondary fragmentation effect behind the armour. That said, it will penetrate two walls of any modern APC at one kilometer range. The trajectory is very flat and does not rise higher than 800 mm above the line of sight when fired to 1000 meters. The cartridge is of somewhat original design, and has plastic case with steel head and base. The projectile is concealed within a plastic sabot.
The rifle itself also is very interesting. Firs, it uses rare long-recoil system, when barrel recoils along with the bolt for significant lenght. At the end of the recoil, bolt unlocks from the barrel by rotating and held back, and barrel returns into forward position, ejecting a spent case. Bolt stays at the rearmost position while barrel moves, and then also moves forward, chambering a new round from the side-mounted magazine and finally locking rigidly to the barrel. This design allows for better recoil disttibution over a longer period of time. Huge muzzle brake also contributes to recoil control, so felt recoil of the IWS 2000 is descibed as a similar to the large-caliber sporting rifle. Five round detachable box magazine is located at the right side of the receiver and inclined down for about 45 degrees. The smooth-bore barrel can be easily detached, so rifle can be carried disassembled into two man-portable packs. Plastics are used where possible to reduce the weight of the gun. IWS 2000 is equipped with bipod and a rear leg under the buttstock. It is also equipped with 10X telescope as a standard.
This is probably the most powerful modern anti-materiel rifle, and while it is not a true "sniper" rifle, it is well worth mentioning. The future of this design is also unclear, sice it requires ammunition of a brand new type.

The LR-300 rifle was manufactured by the small US-based company Z-M Weapons between 2000 and 2007, when all rights for the design were sold to the Para USA, the US-based subsidiary of the Canadian pistol maker Para-Ordnance Ltd. The reworked LR-300 rifle will be sold in USA as Para Tactical Target Rifle, with first sales sheduled to "early 2009".
Original LR-300 (LR stands for Long Range) rifles were designed by Alan Zitta as an upgrade to the well known and popular M16 / AR-15 rifle. In fact, LR-300 and Para TTR both use standard AR-15-type lower receivers; only upper receivers are different and contain patented modified gas system. The key reason for tha modification was to prowide AR-15-type weapon with capability to mount side-folding stock rather than partially collapsible M4 carbine-type stock. Z-M Weapons intended its rifles mostly for military and law enforcement personnel, by offering LR-300-ML weapons with short barrels and select-fire capability. Civilian (semi-automatic only) versions also were offered to general public, but at prices well above the average price of AR-15-type rifle. It is not known yet if the new Para Tactical Target Rifles will also be offfered in military (select-fire) version or not; current Para USA advertising suggests that only semi-automatic weapons (and upper receiver conversion kits) will be offred, at least initially.
The LR-300 rifle is gas operated, and utilizes modified Stoner-type direc gas imingement system. In this modified system, the gas key is extended forward to form the tube, that protrudes forward from the receiver and into the handguard. The protruding part of the gas key tube is used to host the bolt return spring, which is placed between the front receiver wall and the collar at the front of the gas key tube. The gas tube, which runs rearward from the gas block / front sight base, is strengthened as its rear end floats freely to enter the extended gas key tube when bolt group is in the battery. That way, at least some of the hot gases from inside the gas karrier are expelled outside the receiver and into the inner handguard area, through the extended gas key tube, once it has left the gas tube during the bolt group recoil movement. Additional benefit of this system is that it allows the bolt carrier to be made twice as short compared to the standard AR-15-type bolt carrier. In turn, this results in the fact that there's no need for the recoil buffer tube, which is normally protruding backward from the AR-15-type lower receiver. Because of this feature, most LR-300 rifles are fitted with side-folding shoulder stocks, either sceletonized non-adjustableones made from metal or polymer ones, adjustable for length of pull. Otherwise the LR-300 is similar to the AR-15-type weapons and has similar trigger / safety arrangements, magazine housing and bolt stop device.

The SS2 family of rifles (from Indonesian "Senapan Serbu 2" - Assault Rifle 2) is manufactured in Indonesia by PT Pindad factory and is based on SS1 (FN FNC) rifle, made by the same factory under license from Belgian company FN Herstal. SS2 rifles are in use by Indonesian army since 2005, and also are offered for export. Initially available in three basic versions (standard rifle SS2-V1, carbine SS2-V2 and para-sniper SS2-V4) it is now also available in subcompact SS2-V5 version, first shown in 2008.
All SS2 rifles share same basic design and same two-part upper / lower receiver construction. Both upper and lower receiver parts are made from aluminum alloy and connected one to another using two cross-pins. Gas-operated action uses long-stroke gas piston, located above the barrel, and a multi-lug rotary bolt that locks into the barrel extension. Charging handle is attached to the bolt carrier on the right side and moves with the bolt group when gun is fired. Fire mode / safety lever is located on the left side of the gun, and permits for single shots and full automatic fire. All versions are fitted with side-folding skeletonized buttstock, and all variants have integral Picatinny type rail on the top of the receiver. In all versions other than SS2-V4 this rail is fitted with removable carrying handle with diopter-type rear sight. Front sight is attached to the gas block, leaving the muzzle part of the barrel unobstructed, so rifle can be used to fire rifle grenades. The SS2-V4 version is issued less front sight base or carrying handle, being fitted with telescope sight and optional cheek rest on the buttstock. SS2-V4 also features heavier barrel for more accurate long-range fire. SS2-V1 and SS2-V2 variants can be fitted with 40mm under-barrel grenade launcher, also made by Pindad.

SENJATA SERBU BUATAN SINGAPURA STK ULTIMAX
Singapore Technology Kinetics yang di singkat STK ULTIMAX, inilah jawaban pamungkas Singapura atas kecemasan terhadap pertahanan negaranya. Diracang seringan mungkin, bobotnya yang hanya 6,8 kg ketika di muati 100 peluru memang sangat cocok untuk pos tur asia. Menganut prinsip constant recoil, Ultimax memiliki akurasi jempolan dan mudah di kontrol untuk ukuran senjata dikelasnya. Namnjangan dikira ketika baru lahir Ultimax sudah sempurna.
Varian uMk.1 yang lahir pada 1982 hanya dilengkapi laras yang tidak bisa di ganti dan mode penembakan hanya semi-full outo. Sistem feed peluru pun masih menganut sabuk rantai yang rawan macet.
Kelemahan ini baru diperbaiki pada varian MK.3 yang dapat diganti larasnya plus mode penembakan yang sudah menganut safe semi-full auto. Mulai varian Mk.3 pula di perkenalkan Ulimax para dengan panjang laras Cuma 330 mm plus magasin drum yang mengingatkan sekilas kepada senjata buatan Blok Timur.
Ultimax sendiri sempat mencuri perhatian ketika USMC mengadakan kontes untuk mencari kandidat senapan mesin regu. Merasa punya kans, STK membuat versi khusus Ultimax Mk.4 yang dilengkapi dengan adaptor sehingga mampu memakai magazen M16 atau Beta C-Mag 100 Peluru tanpa perlu di modifikasi tambahan. Hasil test menunjukan performa yang sangat superior. Ultimax mampu di tembakkan di tengah-tengah rendaman lumpur sama halnya dengan ak-47 . Akurasi pada penembakan semi otomatik juga mampu membuat grouping yang sama dengan senapan serbu. Sayanya, pertimbangan politis membuat Ultimaz harus mengangkat bendera putih pada M249 SAW yang memang mede in USA
