The JP Enhanced Cam Pin retains every critical Mil-spec dimension of the part but improves on both design and finish. A smoother operating system with lower overall wear in the components is the result. In addition to receiving JP's low-friction QPQ finish, the Enhanced Cam Pins are also machined thicker than the usual undersized dimension of standard pins. An undersized pin drops right in but allows slop in the relationship between bolt, bolt carrier and cam pin. Looseness in these parts stresses the cam pin hole of the bolt during cycling, which is why bolt breakage is so common at this point. It also wears the cam pin faster as the carrier wears into the material at the bearing points. A tighter pin with low-friction coating cuts all this wear down dramatically. Finally, JP holds the upper receiver-to-cam pin width precisely to keep the bolt in alignment with the barrel. This reduces premature lug wear to the barrel extension. These cam pins are available individually and are now the JP standard cam pin wherever JP uses them.
Tighter dimensional tolerances for reduced bolt assembly and cam pin wear
Elimination of sharp edges dramatically reduced wear to the upper receiver
Smoother operation thanks to additional polishing to all critical surfaces
Rock-hard QPQ coating for corrosion resistance and lubricious cycling
Mil-spec compatible requiring no additional proprietary parts
