The Lantac CP-R360 Domed Cam Pin - .223/5.56, from Lantac, features precision machining with two flats cut at 90 degrees to the front face to reduce internal wear in the cam channel, and its unique domed head allows the cam pin to operate from a different position than traditional pins; the radius of the head curves away from the receivers internal surface, preventing a sharp edge from causing wear. Finished in its natural hardened state with a copper/brass color, this pin is designed to maximize longevity and reliability while maintaining smooth operation within Mil-Spec bolt carrier groups and 5.56/.223 platforms. Made in the USA, it is built to withstand sustained, high-volume use in modern sporting rifles and duty-centric builds alike, delivering consistent cycling by minimizing cam-channel resistance and heat-related wear. Ideal for shooters seeking to extend component life, improve cam operation, and preserve accuracy over time, the CP-R360 integrates seamlessly with standard BCGs and complements other Lantac components for trusted performance in everyday shooting, training, and tactical applications.
