10.5-Inch AR-15 Barrels
65 products · page 1 of 3
A 10.5-inch barrel is the classic length for AR-15 pistols and short-barreled rifles: short and handy, but long enough to run 5.56 reliably, usually with a carbine gas system (300 Blackout versions use pistol gas). Most are 5.56 NATO or 300 Blackout, which loses less velocity in a short barrel. On a rifle with a stock, a barrel under 16 inches makes it a short-barreled rifle that needs ATF approval first, so check current federal and state rules before you build.
Compare every 10.5-inch barrel from the stores we track, and add one to your build so MyGunLab can check it against your upper, gas block and handguard.
