The JP stainless bolt carrier is precision machined from 416 stainless steel. The bearing surface area has been increased by 100% resulting in smooth cycling and improved reliability over the USGI unit. It is in semiauto configuration, but with the larger mil-spec cocking pad. The JP stainless AR-15 bolt carrier is ready for tactical/mission critical roles with its forward assist serrations and dust cover notch. The larger exterior bearing surfaces are hand polished to reduce friction to an absolute minimum before the whole unit is given a five-step QRP process which results in an extremely hard wearing, friction reducing black finish. The bore of the AR bolt carrier is non plated and is roller burnished for low drag bolt operation. A gas key is ready installed.
