Our Key-Lock bolt carrier group is comprised of a Nitride heat treated carrier and stainless steel gas key. The gas key is secured with a staked screw and dove tailed into the carrier for an extremely rigid design. This design helps reduce carrier tilt. Our bolt carrier groups feature a chrome plated bolt, extractor, and firing pin. The finishes are both corrosion resistant and introduce lubricious characteristics to the action.
Our patented roller cam pin is a prime example of how we strive to reduce friction and drag in the action. Standard AR cam pins feature a square steel head that literally grinds and carves away at the inside of the receiver. POF’s NP3 coated roller head actually rolls inside the channel of the upper, thus eliminating friction and prolonging the life of the upper.
