The Perfect Pair: FRC Compensator and Suppressors

Posted by Piston Head on Oct 22nd 2024

The FRC compensator by PWS is not just another muzzle device—it's engineered for shooters who demand high performance and suppressor compatibility. Available in both 2-port and 3-port versions, the FRC reduces recoil and makes your firearm more controllable without sacrificing precision. Whether your barrel has a flat or tapered shoulder profile, the line-up of FRC compensators are designed to fit seamlessly on many different calibers and rifle platforms.

Suppressor-Ready Design

When paired with the FRC compensator, suppressor installation becomes an easy and tool-less operation. The tapered external shoulder promotes concentricity with HUB compatible suppressor adapters, ensuring proper bore alignment and preventing the dreaded “baffle strike.” The taper also creates a seal that stops carbon from reaching the threads and causing a seized lockup.

Using popular HUB suppressor adapters like the Rearden ATLAS or Q Plan B, installation is as easy as threading your suppressor onto the FRC to a good hand-tightness. This makes swapping a suppressor onto multiple firearms a much easier feat, especially at the range or in the field.

Enhanced Control: The FRC’s recoil-reducing design keeps you on target, improving your overall shooting experience.
No Timing Needed: While the FRC can be timed, it is not required for efficiency
