This machined, flash hider is 5.5" in length but only gives an AR-15 about 1.5" in length. This device slides over the barrel providing a clean look while protecting the barrel and the threads. This muzzle brake helps to force the signature and muzzle blast at least 1.5" from the end of the barrel without sacrificing performance. See all of the photos for measurements and appearance (gun & other parts sold separately)
