Guntec Micro Slip Over Barrel Shroud Features The Guntec Micro Slip Over Barrel Shroud uses a Gatling gun style multi porting pattern to redirect gas and reduce felt recoil by as much as 70 percent. Machined from US made T6 aluminum the shroud is built to handle the stresses of repeated firing while keeping total weight to just 3.2 ounces. Its 0.625 inch inner diameter is sized to slip directly over a .308 or .300 AAC Blackout barrel with threads beginning approximately 1.25 inches down the shroud. Functioning as both a barrel shroud and a muzzle compensator this dual purpose design covers 1 and 5/8 inches of barrel while adding recoil control in a single compact unit. At just 3 inches long with a 1.1875 inch outer diameter the shroud keeps a low profile well suited to AR pistol builds where overall length matters. The anodized black finish matches typical AR platform hardware for a clean consistent appearance. Built for 5/8x24 threaded barrels this shroud installs by slipping over the barrel and threading down from the inside a simple process for home builders and gunsmiths alike. Designed specifically for use on AR pistols the Guntec Micro Slip Over Barrel Shroud gives shooters a compact way to manage recoil and muzzle rise.
