The Shaw Barrels AR-15 6mm ARC replacement barrel gives AR-15 builders a premium-grade option for the versatile 6mm ARC cartridge. This barrel features a 12.5" HBAR (Heavy Barrel) profile cut from 416R stainless steel with a non-glare matte finish.

Rifled with 6 grooves at a fast 1:7.5 twist to stabilize a wide range of 6mm ARC bullet weights, this barrel is machined with a 0.75" gas block journal and is not chrome-lined. The muzzle is threaded 5/8x24 for attaching a compensator, muzzle brake, or suppressor.

Proudly made in the USA by Shaw Barrels' experienced craftsmen, this HBAR 6mm ARC barrel is an excellent foundation for a compact, hard-hitting AR-15 build.
