The JP Enterprise PSC-11 upper receiver assembly
features JP's innovative non-reciprocating side charging handle
, and retains the standard charging handle. The side charger has a large, wide handle for quick and easy operation, but it is spring loaded and contoured as to not catch on chest rigs or other gear. The standard charging handle remains functional, for compatibility for all users, and functionality with any mil-spec lower receiver. The lightweight barrel
is made of 416 stainless steel
, button rifled and cryogenically treated
for outstanding accuracy. The 223 Wylde
chamber is designed to be best of both the SAAMI commercial specification and the NATO chambering, allowing the widest variety of ammunition to be used, while retaining accuracy. The 1 in 8" twist
rifling produces good results with bullet weights from 40 to 77 grains. The 14.5" barrel
has a YHM Phantom compensator pined and welded
for a permanent attachment to bring the barrel to 16" in length. The Full Mass bolt carrier
is constructed of 416 stainless steel, with a roller burnished interior and hand polished exterior for slick operation when properly lubricated. The SAE 9310 steel bolt
exceeds the standard mil-spec in strength and service life. The JP VTAC Modular handguard
is a reduced diameter free-floating handguard with provisions for mounting accessory rails in many positions. The reduced 2" diameter of the handguard makes it more comfortable in the hand and allows for better control of the rifle. The large ventilation slots keep the barrel cool and reduce the weight 20% over conventional tubes.
