This video provides an in-depth review of the Parker Mountain Machine (PMM) Ultra Comp, highlighting its effectiveness in reducing muzzle rise and improving shooting flatness. The presenter, Brett from Nightwood Guns, details its performance compared to other compensators, discusses reliability with various ammunition types, and offers a critical look at its installation process, finish durability, and significant point-of-impact shift with different loads. While highly recommending it for competition or standard pressure ammo users, the presenter explains why the POI shift makes it unsuitable for his personal carry setup with +P ammunition.
