From the manufacturer

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 threa Mfg: Criterion Barrels Inc SPECS: Fits - DPMS pattern 308 rifles.
