PRECISION CAM PIN
A Precision Cam pin with tighter tolerances compared with the standard milspec component, providing improved shot to shot consistency in AR platform weapons. The cam pin head features a directional arrow for uniform lapping, and is designed to minimize upper receiver contact when not used in conjunction with the Long Advance Bolt Carrier, while providing full bolt stability and control.
CORRECTED TIMING
By correcting the legacy cam path, the bolt unlocks at 22.5 degrees rather than 20.7 degrees ensuring the cam pin is at top-dead-center where it should be, thus avoiding interference with the receiver wall aft of the the cam pin recess. By delaying unlocking by almost 2 degrees, residual chamber pressure is reduced allowing the cartridge to fully release from the chamber wall easing extraction. The long advance cam path results in a flatter shooting platform with less recoil, even in over-gassed weapons, and smoother locking and unlocking all reducing muzzle rise.
