Knight's Armament SR-47
The Knight's Armament Company SR-47 is a variant of the AR-15 family chambered in 7.62x39mm. The SR-47 was originally a contender (and eventual winner) of the Special Purpose Receiver - Variant (SPR-V) program. It was originally intended to be a set of drop-in parts that could convert the M16 rifle or M4 carbine in the field to feed 7.62x39mm ammunition from captured Kalashnikov-system magazines. The resulting item, if approved, would have been added to the SOPMOD kit. The eventual development process revealed that the resulting receiver would be too big to be a separate parts kit, so the requirement was changed to a dedicated weapon system called the Special Purpose Rifle - Variant.
Only seven prototypes were ever made - six for field testing by a SEAL team and one example for the firearms collection in Knight Armament's museum. The weapon was never adopted as a standard or special issue item and a proposed SR-74 version chambered for 5.45x39mm failed to be approved. Major flaws in the concept behind the weapon may have been to blame. Unlike American and allied forces, enemy ammunition used corrosive primers. This would damage the barrel and gas system if not regularly cleaned after use. The weapon would also have to use magazines picked up off of enemy combatants which might be old, badly worn, or even damaged from improper handling and may not be as reliable as their issued magazines, which led to many reports of frequent failure to feed malfunctions.
