AR-15 Bull & Heavy Barrels
51 products · page 1 of 2
Bull and heavy-profile (HBAR) barrels are thicker than standard barrels. The extra steel keeps them stiff and accurate as they heat up, which suits varmint, target and precision rifles shot from a bench or bipod, at the cost of weight out front. A true bull barrel keeps the same thick diameter end to end; heavy and HBAR profiles keep most of that thickness, especially forward of the gas block, and fluted versions shave some weight. Check the gas block size: many heavy barrels use .750 or .875 inch.
Compare bull and heavy barrels below, and add one to your build so MyGunLab can check it against your gas block and handguard.
