The Primary Weapons Systems FRC 2-Port Compensator is a muzzle device built around a specific mission: taming recoil while keeping your sight picture clean. This 1/2"x28 compensator threads directly onto .223 Rem rifles and serves double duty as both a standalone brake and a suppressor host for compatible sound suppressors. The tapered-shoulder design fits barrels with a recessed or tapered profile behind the muzzle threads, giving you precision fitment without requiring barrel modifications.
The 2-port design is where the FRC earns its keep on the range or in tactical scenarios. By directing muzzle flash away from your optics and line of sight, it keeps your zero visible during rapid strings and low-light shooting. This matters whether you're running a red dot, magnified optic, or irons. The ports are angled to work the physics of recoil reduction—controlling muzzle rise so follow-up shots land faster and more consistently. Pair it with a suppressor and the FRC provides a robust, tight lockup that holds through sustained shooting without walking or shifting.
At 1.80" overall length, it won't extend your barrel profile excessively, keeping your rifle handling snappy. The black finish is durable and matches standard AR-15 furniture. Whether you're building a dedicated suppressor host, running it bare on a mid-length upper for flash management, or looking for a rock-solid foundation for sound signature reduction, the FRC gives you a compact, field-proven option.

Yes. The FRC 2-Port Compensator is designed to function as a suppressor host and will accept compatible sound suppressors. Check your suppressor's mounting interface to confirm compatibility with 1/2"x28 threaded mounts.
The tapered-shoulder design (this model) fits barrels that feature a recessed or tapered profile behind the muzzle threads. If your barrel has a traditional flat shoulder, you would need the flat-shouldered variant instead. Measure your barrel's profile to confirm which fits your setup.
Yes. This compensator is threaded 1/2"x28, the standard pattern for .223 Rem and 5.56 NATO rifles. It will fit any barrel with that thread pitch.
The two ports redirect muzzle gases and flash away from your optics and sight line, keeping your view clear during strings of fire. This geometry also works to reduce muzzle rise and recoil impulse, helping you stay on target for faster follow-up shots.
