Axem Cam Pin - AR-15 spare part for 5.56/.223 caliber bolt carrier group; phosphate-coated cam pin that guides bolt rotation and locking timing. Compatible with standard bolts of 5.56 NATO and .223 Rem systems and designed to replace worn or damaged cam pins without fitting. Phosphate coating enhances wear resistance and lubrication retention.
Precisely machined and heat-treated structure ensures repeatable motion and low friction in the carrier's cam channel. Hardened steel withstands impacts and continuous load, and the hole is finished to allow the firing pin to move freely. Precise dimensions support smooth assembly and operational reliability.
The phosphate surface (manganese phosphate, or parkerizing) provides a microstructure that retains oil and reduces wear over time. Matte finish reduces glare and protects against mechanical wear. Drop-in installation is achievable with standard maintenance methods: the cam pin is rotated 90 degrees in the bolt, removed, and the new part is installed in the reverse direction.
Compatibility is designed for AR-15 system 5.56/.223 bolts and standard carrier bodies. Not intended for AR-10 platforms. During maintenance, light oiling of the cam pin surface is recommended before assembly to ensure smooth motion and minimal wear.
