MRAT Compensator for FN Reflex Pistol

If you’re shooting an FN Reflex and finding that snappy muzzle rise is slowing down your follow-up shots, the MRAT Compensator is a direct fix. This is a thread-on compensator designed specifically for the Reflex barrel. It works by redirecting propellant gases through angled ports to push the muzzle back down, reducing felt recoil and muzzle rise by a claimed 30-40% depending on the ammunition you’re running. The result is faster sight recovery between rounds and less “trigger pinch” after each shot—the kind of practical improvement that makes range time more productive and a lot more fun.

Compatibility

• FN Reflex (full-size and compact models with threaded barrel)
• Direct thread-on fit—no adapter or barrel modification needed
• Do not use with hand-loaded ammunition below SAAMI spec pressure

Key Features

• Unique angled port design redirects gases upward to reduce muzzle rise by 30-40%
• Built-in clamp is Wire EDM cut into the comp body—mounts and removes without thread locker
• Clamp screws torque to 25 in-lb (use a torque wrench, not a guess)
• Wings on the comp body cover the gap between slide and comp for a clean, streamlined look
• Tested with SAAMI spec ammunition from light target loads to +P duty rounds

Install Difficulty

Difficulty: 2 out of 5 — This is a straightforward install if you’re comfortable with basic gunsmithing tools. You’ll need a torque wrench (inch-pound), a hex key for the clamp screws, and a vise or bench block to hold the barrel steady. No thread locker required, which saves you cleanup time. Plan on 10-15 minutes if you’ve got the tools.

Frequently Asked Questions

Will this fit my FN Reflex without special tools?

Yes, it threads directly onto the factory threaded barrel. You’ll need a torque wrench to set the clamp screws to 25 in-lb, but no barrel fitting or adapter is required.

Does it work with +P ammunition?

Yes, this comp was tested with a variety of SAAMI spec ammunition, including +P duty loads. It’s designed to handle the pressure. Just avoid hand loads that fall below SAAMI spec pressure, as they may cause cycling issues.

Do I need to use thread locker on the mounting screws?

No. Do not use thread locker on the MRAT threads or clamping screws. The built-in clamp design holds securely without it, and thread locker can actually cause problems with removal later.
