Guntec USA AR-10 .308 Cal 5/8x24 Slip Over Barrel Shroud w/ Multi Port Muzzle Brake

The Guntec USA 1326MBP308 is a .308 caliber slip-over barrel shroud that doubles as a multi-port muzzle brake, giving .308 / 300 AAC Blackout AR-platform shooters a dual-purpose unit that cools the barrel and tames recoil at the muzzle.

Machined from T6 aluminum and finished in anodized black, this shroud slips directly over the barrel and threads on from the inside, drawing heat away from the bore during extended strings of fire. The integrated multi-port compensator vents gas in a Gatling-style pattern to reduce felt recoil and keep the muzzle flat for faster follow-up shots.

Built for .308 Winchester / 300 AAC Blackout AR-pattern barrels with 5/8x24 threading, the shroud covers 4" of barrel and extends the overall length by 1.5", with an outside diameter of 1.1875" - plan on a free-float handguard with an internal diameter of at least 1.2" to clear it. The muzzle device threads begin approximately 1.25" down inside the shroud body.

Weighing just 6 oz and proudly made in the USA, the 1326MBP308 is a straightforward, no-nonsense upgrade for any .308 AR build where recoil management and barrel cooling are priorities.
