SOLGW bolts are made from Carpenter 158® Steel. Each bolt is HP/MPI tested and inspected. Each bolt is shot peened and comes with a heavy extractor spring, black spring insert and O-Ring. The bolt and cam pin have been NP3 treated to enhance corrosion resistance and carbon build up.
Our M16 profile Bolt Carriers are machined to USGI specifications. Our M16/M4 carriers include proper Mil-Spec gas keys. The Gas Key is heat treated per GI specifications and NP3 coated. The Gas Key is secured to the carrier via USGI domestic manufactured Grade 8 fasteners and properly staked per Military Specifications. These properly hardened parts insure a strong staking and proper gas system functioning.
Each carrier assembly is treated with a durable Nickel/PTFE plating which creates a permanently lubricious surface which reduces the need for lubrication.
