JP Enterprises JP-15 .223 Wylde 16in Complete Upper The JP Enterprises JP-15 complete upper is a small-frame, top-charge .223 Wylde assembly, available now at Battlehawk Armory in matte black. It uses a 16-inch SuperMatch light-contour barrel with a 1:8" twist, mid-length gas system, and black Teflon finish under a black 3-port JP compensator (1/2x28, .750" OD, .281" exit). A forged top-charge upper and a Radian Raptor-LT charging handle keep the package simple and familiar to AR-15 shooters. A 15.5-inch rock-blasted M-LOK handguard covers a low-profile .750" JP adjustable gas block with detent in black stainless. The bolt group is a full-mass JP small-frame carrier with a DLC enhanced .223 bolt and a standard .223 firing pin. Mid-length gas and the adjustable block give you a way to tune the upper for suppressors or a range of factory loads without swapping springs first. This is a complete upper only-no lower, stock, or magazine. It is ready to pin to a mil-spec AR-15 lower.
