This is considered the best bolt carrier group available on the market today. 

Compatible with any standard Mil-Spec upper! This bolt carrier group is for any application where absolute reliability is the main criteria, the FMOS™ or Full Mass Operating System with 416 stainless steel special design carrier that includes forward assist serrations and a dust cover notch. The bore of the JP stainless carriers has a roller burnished finish for frictionless operation with no chance of peeling chrome as in standard mil-spec carriers. The exterior bearing surfaces are hand polished. When properly lubricated, both systems make your rifle feel like it was cycling on ball bearings.

The JPBC-2 bolt carriers provide a100% increase in bearing surface for smoother operation and improved alignment and lower wear in the upper receiver. Both are AR-15 semi auto configuration in the rear with the mil-spec longer cocking pad in the front for best reliability. This is the best designed and highest quality general purpose carrier on the market. Sold as carrier, bolt, and parts with installed key.

The latest edition JP EnhancedBolt™ is made from SAE 9310 high-grade steel. This material makes for an extremely hard surface with a tough, ductile core resistant to structural failure and a life expectancy far exceeding Mil-spec 8620-type bolts. SAE 9310 is the same type of steel used in the transmission gears of Formula One racecars, and the high-load application of a bolt assembly is ideal for this state-of-the-art material; the results of actual full-auto endurance torture tests prove it.
