MRAT Compensator for FN Reflex Pistol

The MRAT Compensator for the FN Reflex pistol is a direct thread-on muzzle device built to cut muzzle rise by 30-40% (depending on ammunition). If you shoot fast and want to stay on target without fighting the gun, this compensator delivers real, measurable results. No gimmicks — just a proven design that works.

Key Specs & Fitment

• Direct thread-on design specifically for the FN Reflex pistol
• Reduces muzzle rise by 30-40% with standard SAAMI spec ammunition
• Works with target rounds, +P duty loads, and everything in between
• Hand loads with less than SAAMI spec pressure may cause malfunctions — stick with factory or properly loaded ammo
• Clamp screws must be torqued to 25 in-lb — no thread locker needed or allowed
• Wings on the compensator body cover the gap between slide and comp for a clean, streamlined look

How It Works
The MRAT uses a unique angled port design that redirects gases upward. This directly counteracts muzzle flip and reduces felt recoil. Less muzzle rise means faster sight recovery between shots — you spend less time fighting the gun and more time putting rounds on target. Our testers also reported a reduction in “trigger pinch” after each shot. By keeping the muzzle down, the compensator lessens the snappy feel that can cause your finger to pinch against the trigger guard. The result: more comfort and more fun at the range.

Mounting Method — Built for Speed and Reliability
This mounting system is the result of nearly two years of testing. The built-in clamp is Wire EDM cut into the profile of the compensator. This allows fast, secure mounting and removal from the barrel — no thread locker compounds needed. You can take it off for cleaning or suppressor use without fighting stubborn residue. The two clamping screws are positioned on opposite sides of the barrel threads, ensuring equal clamping force on both sides. This prevents the compensator bore from becoming misaligned, so you get consistent performance every time.

What You Get

• Reduced felt recoil — less snap, easier control
• Reduced muzzle rise — 30-40% improvement, depending on ammo
• Faster sight return — stay on target between rounds
• Streamlined profile — wings cover the slide-to-comp gap
• Tool-less removal — no thread locker, easy to swap or clean

Important Installation Note
Do not use thread locker on the MRAT threads or clamping screws
