Guntec Multi Port Compensator Features The Guntec USA Multi Port Compensator is machined entirely from steel to withstand the higher pressures and heat generated by .308 Win and .300 AAC Blackout cartridges. Its multi port design vents expanding gas through several angled openings which works to counteract muzzle rise and reduce felt recoil compared to shooting without a muzzle device. Less muzzle rise means faster recovery between shots which directly improves follow-up shot speed for rifle shooters working larger calibers. The matte black finish is durable and matches most standard AR-15/AR-10 pattern rifle finishes. Hex grooves cut into the exterior of the compensator make installation and removal straightforward with a standard wrench without needing a specialty spanner tool. The 5/8x24 thread pitch is the standard pattern for .308 Win and .300 AAC Blackout barrels so it threads directly onto most common aftermarket and factory barrels without an adapter. This straightforward no-frills design makes the compensator an easy add for shooters building or upgrading a .308 or .300 Blackout AR pattern rifle. Anyone looking to tame recoil on a heavier caliber AR build will find this compensator a practical affordable option.
