Shaw Barrels Barrel Features The Shaw Barrels Barrel is machined from 416R stainless steel a material prized among precision rifle builders for its combination of corrosion resistance and machinability for tight-tolerance rifling. The bead blast matte finish gives the barrel a low-glare surface that still showcases the stainless steel s natural corrosion resistance. Its rifle-length gas system and .750 inch dimpled gas journal are matched to the HBAR profile for reliable cycling across a range of .22 Creedmoor loads. The 1:8 twist rate is well suited to the heavier higher-ballistic-coefficient bullets that make .22 Creedmoor attractive for long-range shooting. At 20 inches and 3.15 lbs the barrel s HBAR contour adds stiffness that helps maintain accuracy as the barrel heats up during strings of fire. The 1/2x28 threaded muzzle accepts a brake or suppressor giving AR-10 builders flexibility in muzzle device selection. This barrel is made in the USA and built to fit the DPMS LR-308 Gen1 pattern upper receiver making it a straightforward swap for compatible AR-10 builds. For shooters chasing long-range accuracy from an AR-10 platform the Shaw Barrels .22 Creedmoor barrel offers a corrosion-resistant precision-oriented upgrade.
