JP Bolt Complete BCG including JPBC-2 .223 full mass carrier and JPEB-223 enhanced
FMOS Bolt Carrier
Feature a 100% 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 hands-down the best designed and highest quality general purpose carrier on the market.
Made from 416 stainless steel, this special design carrier 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 also polished so that, when properly lubricated, both systems make your rifle feel like it was cycling on ball bearings.
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 C-158 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.
The design of the JP EnhancedBolt™ addresses many other fine points, the most important of which is the utilization of a standard configuration extractor. Most users want the ability to replace extractors and other parts with commonly available Mil-spec parts instead of being dependent on proprietary parts that can be difficult to acquire. Therefore, this new bolt will accept standard extractors, pins and springs.
