The Sons of Liberty Gun Works 6mm ARC Bolt Carrier Group is a precision-engineered component built for AR-15 platform rifles chambered in 6mm ARC, .22 ARC, .338 ARC, and 6.5 Grendel. Featuring a 9310 steel bolt with a nitride finish for exceptional hardness, wear resistance, and corrosion protection, paired with a phosphate (Parkerized) coated carrier for long-lasting durability in the field. The nitride treatment on the bolt provides a slicker surface that promotes smoother cycling and easier cleaning, while the phosphate carrier ensures reliable performance under sustained fire and adverse conditions. With a properly staked gas key secured by Grade 8 fasteners, this BCG is built to the exacting standards that Sons of Liberty Gun Works is known for, making it an excellent choice for precision shooters and hunters looking to get the most out of their intermediate cartridge AR-15 builds.
