AR-15 Carbon Fiber Barrels

A carbon fiber barrel wraps a thin steel barrel (the liner) in carbon fiber. The result is stiffer than a steel barrel of the same weight, so you get much of a heavy barrel's accuracy without carrying the weight out front. They cost more than all-steel barrels and are most popular on lightweight hunting, precision and competition builds. As with any barrel, check the caliber, gas system length and gas block size before you buy.

Compare carbon fiber barrels from every store we track, and add one to your build to check it against the rest of your parts.
