The Sons Of Liberty Gun Works NTC Bolt Carrier Group, 5.56 NATO/.300 Blackout, delivers a smooth-running, low-maintenance upgrade for AR-15 platforms. Featuring a Nickel Teflon Coating on the bolt, carrier, ejector, and cam pin, this BCG is engineered for extended service life, excellent lubricity, and strong corrosion resistance while maintaining a full-auto M16 carrier profile.

This bolt carrier group is built around a Carpenter 158 steel bolt that is shot peened, high pressure tested, and magnetic particle inspected, with OCKS gas key screws and a chrome-lined gas key and carrier bore for dependable gas sealing. Ideal for hard-use range rifles, training carbines, and duty-style builds in 5.56 NATO or .300 Blackout, it offers consistent performance with easier cleanup, especially on suppressed setups. Sons Of Liberty is known for producing durable, no-nonsense components that meet professional standards.
