Guntec Slip Over Barrel Shroud Multi Port Muzzle Brake Features The Guntec USA Slip Over Barrel Shroud is machined from T6 aluminum and threaded 5/8x24 to slip over and secure onto a .308 or .300 AAC Blackout caliber barrel. Its gatling gun style multi port design is engineered to reduce felt recoil by as much as 70 percent which helps keep the muzzle flatter and allows for faster more controlled follow-up shots. The shroud covers roughly 4 inches of the existing barrel while extending overall barrel length by 1.5 inches giving the rifle a more aggressive profile without permanently altering the factory barrel. At 5.5 inches long and a 1.1875 inch outer diameter the shroud is sized to fit comfortably on most .308 pattern rifles. Functioning as a true dual purpose device the shroud works as both a barrel shroud protecting the shooter s support hand from heat and as a functional compensator managing recoil and muzzle rise. The anodized Black finish matches most factory and aftermarket barrel finishes while resisting wear from heat and handling. Weighing only 6 ounces the device adds minimal weight to the front of the rifle despite its dual function design. Made in the USA the Guntec USA Slip Over Barrel Shroud is for sale at GrabAGun for .308 and .300 AAC Blackout shooters looking to reduce recoil and add barrel protection in one part.
