Pindad SS2

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.
