JP Enterprises Enhanced Cam Pin AR-15 .223 A Mil-Spec Dimensions A QPQ Coating A Polished Critical Surfaces A JPCP-223 The JP Enterprises Enhanced Cam Pin retains all critical mil-spec dimensions while improving design and adding a low-friction QPQ finish. Sharp edges eliminated to dramatically reduce upper receiver wear. All critical surfaces polished for smoother operation. Upper receiver-to-cam pin width held precisely to maintain bolt alignment with the barrel-reduces premature lug wear to the barrel extension. Rock-hard QPQ coating for corrosion resistance and lubricious cycling. Mil-spec compatible-no additional proprietary parts required. SKU: JPCP-223. Mil-Spec Dimensions Retains every critical mil-spec dimension for drop-in compatibility with AR-15 bolt carrier groups. No proprietary components required. Sharp Edge Elimination Sharp edges eliminated to dramatically reduce wear on the upper receiver. The improved geometry distributes load more evenly during bolt cycling. Precise Width Tolerance Upper receiver-to-cam pin width held precisely to keep the bolt in alignment with the barrel. Reduces premature lug wear to the barrel extension over standard mil-spec cam pins. QPQ Coating Rock-hard QPQ coating provides corrosion resistance and lubricious cycling. Lower overall friction and wear compared to standard mil-spec cam pins.
