Guntec AR-15 Mini Slip Over Barrel Shroud Features The Guntec USA AR-15 Mini Slip Over Barrel Shroud measures just 2 3/8 inches long and covers 1 3/8 inches of the barrel with threads beginning approximately 1.25 inches down the shroud so it slips over and locks down from the inside. This micro design keeps the overall footprint small making it especially well suited for AR pistol builds where overall length is a priority. The multi port Gatling gun style venting directs gas outward to help tame muzzle rise and felt recoil with Guntec rating the reduction at up to 70 percent. At an outside diameter of 1.1875 inches and a total weight of just 2.9 ounces it adds minimal bulk to the front end of the build. Machined from US made T6 aluminum and finished in anodized black the shroud is built to handle the heat and wear of regular use while matching the look of most black AR builds. It is cut with a 1/2x28 thread pitch for standard .223/5.56 caliber barrels and will also fit 9mm barrels sharing that same thread pattern. Because it functions as both a barrel shroud and a muzzle compensator in one unit shooters get recoil control and barrel coverage without stacking separate parts on the muzzle. This compact dual purpose muzzle device is available for sale at GrabAGun for AR-15 and AR pistol owners looking to manage recoil in a short low profile package.
