AK-103

 

The AK-103 assault rifle is a derivative of the AK-74M chambered for the 7.62×39mm M43 round, similar to the older AKM. The AK-103 can be fitted with a variety of sights, including night vision and telescopic sights, plus a knife-bayonet or a grenade launcher. It uses plastic components where possible instead of wood or metal.

Protective coatings ensure excellent corrosion resistance of metal parts. Forearm, magazine, butt stock and pistol grip are made of high strength plastic. The AK-104 is a compact version of the AK-103. It has a muzzle brake derived from the older AKS-74U combined with a shorter barrel. It is also chambered for 7.62×39mm ammunition.

Pindad SS2

The SS2 (short for Indonesian: Senapan Serbu 2, "Assault Rifle 2") is a replacement for the Pindad SS1 created by PT Pindad. It had been seen during the ASEAN Army Rifles contest by foreign media in 2006 aside from exposure by local Indonesian media.

The SS2 assault rifles are currently being pressed into service with the Indonesian military and police. They will gradually replace the SS1 assault rifles which have been in service with the security forces since the 1990s.

The SS2 is an upgrade of the Pindad SS1, being a licensed version of the FN FNC. The SS2's flash suppressor is based on that of the Colt M16A2, and it has a reciprocating charging handle that can be used for forward assist, with the front sight being based on the AK rifles. The carrying handle and detachable rear sight is placed on top of Picatinny railings. Most of the SS2 rifle variants can have its carry handle removed in order to gain access to its picatinny railings to install various optics.

The rifle's front handguard is of a ribbed design, with heat ventilation holes. This design improves barrel cooling in situations when sustained fire is performed. The SS2's barrels were originally produced in Germany before Pindad switched to South Korean-made barrels due to arms embargo problems at the time. The charging handle is on the right side of the SS2 with the fire/safety selector on the left side with provision for single and full auto fire alongside safe mode. Upper and lower receivers are made from aluminum alloy and are connected via cross pins.

Heckler & Koch G36

The G36 is a 5.56×45mm assault rifle, designed in the early 1990s by Heckler & Koch in Germany as a replacement for the heavier 7.62mm G3 battle rifle. It was accepted into service with the Bundeswehr in 1997, replacing the G3. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine.

The G36 is a selective-fire 5.56 mm assault rifle, firing from a closed rotary bolt. The G36 has a conventional layout and a modular component design. Common to all variants of the G36 family are: the receiver and buttstock assembly, bolt carrier group with bolt and the return mechanism and guide rod. The receiver contains the barrel, carry handle with integrated sights, trigger group with pistol grip, handguard and magazine socket.

The G36 employs a free-floating barrel (the barrel does not contact the handguard). The barrel is fastened to the receiver with a special nut, which can be removed with a wrench. The barrel is produced using a cold hammer forging process and features a chrome-lined bore with 6 right-hand grooves and a 1 in 178 mm (1:7 in) rifling twist rate. The barrel assembly consists of the gas block, a collar with a bayonet lug that is also used to launch rifle grenades and a slotted flash suppressor.

The weapon can be stripped and re-assembled without tools through a system of cross-pins similar to that used on earlier HK designs. For cleaning purposes, the G36 dismantles into the following groups: receiver housing, return mechanism, bolt carrier group and trigger group.
