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.

Sons Of Liberty Gun Works was founded on the principle of producing hard use, purpose built weapons for Americans in 2012. Our company was founded by two lifelong firearms enthusiasts and one US Navy SEAL. We produce a wide range of products including M4 based rifles and Mk10 Rifles, over take on the classic AR-10.  

All our products are backed by a LIFETIME Warranty.  We can do this because we believe in only providing products that we believe in and would stake our reputation on.  Our entire staff has been thoroughly trained by the best armorers in the proper procedures to build and diagnose problems with the M4 platform.  

We provide in house custom rifle builds, repairs, cerakote, special order of non AR Platform firearms, training on the AR platform and consulting work.  Come by and check us out, our doors are always open and the after hours beers are always cold.
