This video reviews the Parker Mountain Machine (PMM) Ultra Comp, highlighting its effectiveness in reducing muzzle rise and recoil. The presenter, Brett from Nightwood Guns, details its performance compared to other compensators, noting its superb efficiency. However, he also discusses significant drawbacks, including a difficult installation requiring Red Loctite and precise timing, potential PVD finish wear, and a substantial point of impact shift with different ammunition types, which ultimately leads him to remove it from his personal firearm.

Quick Summary

The Parker Mountain Machine Ultra Comp is a highly effective dual-port compensator that significantly reduces muzzle rise and recoil, making firearms shoot flatter and softer, especially when combined with a DPM Systems recoil reduction system. However, its installation is complex, the PVD finish may wear quickly, and it can cause a substantial point of impact shift between different ammunition types.

Frequently Asked Questions

What makes the Parker Mountain Machine Ultra Comp effective?

The PMM Ultra Comp is a dual-port compensator that excels at redirecting gases to significantly reduce muzzle rise and recoil, leading to a flatter and softer shooting experience. Its effectiveness is further enhanced when paired with a DPM Systems recoil reduction system.

What are the main drawbacks of the PMM Ultra Comp?

The primary drawbacks include a difficult installation requiring Red Loctite and precise timing, potential for the PVD barrel finish to wear quickly, and a significant point of impact shift (up to six inches) between different ammunition types, especially standard pressure and +P loads.

Is the PMM Ultra Comp difficult to install?

Yes, installation is considered difficult. It requires Red Loctite, shims for precise timing and alignment, and must be perfectly clocked to avoid malfunctions. Many users opt for a gunsmith to ensure proper setup.

Who should consider the PMM Ultra Comp?

The PMM Ultra Comp is recommended for competition shooters or individuals who primarily carry standard pressure ammunition. Its high performance in recoil reduction makes it ideal for those seeking maximum efficiency, provided they can manage the POI shift or use consistent ammo.
