High-Performance, B/C Groups In Choice Of Full- Or Low-Mass Configuration
Precision-machined, stainless bolt-and-carrier group features JP’s enhanced bolt made of high-grade 9310 steel for a significantly longer life expectancy than standard mil-spec bolts. Set is available with choice of a JPBC-3A Low Mass carrier that reduces felt recoil and increases bolt speed slightly for enhanced rapid fire handling, or with a standard JPBC-2A Full Mass carrier that replicates the normal carrier weight and is preferred for duty rifles or any time absolute reliability is required. Standard weight carrier features a 100% increase in bearing surface for smoother cycling and reduced wear on the inside of the receiver. Both carriers feature JP’s super-hard QPQ finish for maximum wear resistance and minimal friction. Extractor, firing pin, and all other components are included.High-Performance, B/C Groups In Choice Of Full- Or Low-Mass Configuration
