308 AR STAINLESS STEEL BARRELS Reviews & Ratings

Criterion Hybrid contour match grade .308 AR barrels offer an ideal configuration for those seeking extreme accuracy without the added weight of a heavy barrel contour. These .308 AR barrels feature a M118LR chamber. The longer throat of the M118LR enables Criterion .308 AR barrels to improve upon the performance of loads utilizing heavier bullets, serving to reduce wind drift when fired at longer ranges. This configuration is designed to accommodate either .308 Winchester or 7.62x51 ammunition, and comes complete with an installed barrel extension. CBI .308 AR barrels are compatible with DPMS, Remington, and Fulton pattern rifles, and accept muzzle devices with a 5/8x24 thread. An indent is provided opposite the gas port to enable easy installation. Chambers are finished, but headspace should be checked prior to installation. Stainless steel variants are available in 20 and 22 inch lengths. These barrels are button rifled, and have been hand lapped to ensure consistent bore uniformity. The 20" Hybrid utilizes a 0.750" gas block, while the 22" Hybrid utilizes a 0.875" gas block - gas blocks NOT included.

SPECS: Fits - DPMS pattern 308 rifles. Contour - Hybrid. Cartridge - 308 Winchester. Finish - Stainless Steel. Muzzle Threads - 5/8-24. Gas Block Diameter - .875" for 22" barrel. Twist - 1-11

Not consistent accuracy

I've bought two of the .308 Criterion barrels, and one 6.5 Creedmoor barrel. The one .308 20" chrome lined bore was very accurate and consistent, as was the 22" stainless Creedmoor. The 22" .308 stainless 'target barrel' does ok for the first three shots, then groups get erratic. I'm thinking it warps from the barrel heating up a bit. Aero matched upper and lower, all quality parts, no junk, just not so good on this barrel
