Bushing-mount muzzle brake compensator for the 5" Government-length 1911 in .45 ACP. Replaces the factory barrel bushing with a ported compensator that vents gas upward and back, reducing muzzle rise and shortening the reset for follow-up shots.

• Calibers up to and including .45 ACP; also works on .38 Super and 9mm 1911 conversions

Does NOT fit

• Bull-barrel 1911 designs
• Threaded / suppressor-ready barrels

• Bushing-style compensator — no barrel threading required

Install notes

Minor fitting to the barrel lug may be required for a tight lock-up. A gunsmith fit is worth the small cost if the pistol will see match use.
