From the manufacturer
Without filing paperwork with the ATF, AR-15 barrels must measure at least 16 inches long, and once you add in a muzzle device, you've got a rifle barrel that might not be as nimble as you want it. Pinning a muzzle brake to a short, 14.5-inch barrel can bring the overall length up past 16 inches, but once that brake is pinned, there's no going back. However, the Aero Precision Epsilon 556 SL Muzzle Brake makes that permanence a bit easier to live with. Each Aero Precision Epsilon 556 SL Muzzle Brake measures 0.745 inch in diameter, which matches the profile of many popular AR-15 barrels on the market. This means that there's a seamless transition between the brake and the Mfg: Vg6 Precision
