The Guntec Multi Port Compensator (brand part number SIG210-308) is built for .308 and .300 AAC Blackout AR-platform rifles, using multiple ports to redirect gas and cut down felt recoil. All-steel construction stands up to the heavier recoil impulse these calibers produce, and hex grooves machined into the body make for easy tightening with a standard wrench. Threaded 5/8×24 and finished in matte black, it’s a straightforward bolt-on upgrade for AR-308 pattern rifles.
