Shaw Barrels AR Barrel Features The Shaw Barrels AR Barrel is machined from 416R stainless steel a material prized for its combination of accuracy potential and corrosion resistance in precision rifle barrels. Chambered in 6mm ARC the barrel is paired with a 1 in 7.5 inch twist rate that is fast enough to stabilize heavier high ballistic coefficient 6mm ARC bullets at extended ranges. The 16 inch length places the barrel in mid length gas system territory giving builders a platform that balances velocity retention with a more maneuverable overall rifle length. An HBAR profile adds mass along the barrel for added rigidity and heat management during sustained strings of fire. A 5/8x24 threaded muzzle gives the builder the flexibility to run a compensator muzzle brake or suppressor adapter of their choice on the finished rifle. The bead blast matte finish provides a durable non reflective surface that resists glare in the field without adding the cost of a full coating process. At 2.40 pounds the barrel keeps the front end of a 6mm ARC build manageable for offhand and supported shooting alike. For a shooter building a dedicated 6mm ARC precision rifle the Shaw Barrels AR Barrel offers the metallurgy twist rate and profile needed to get the most out of the cartridge.
