MRAT Compensator for FN Reflex Pistol

The MRAT Compensator for the FN Reflex is a direct thread-on muzzle device engineered to reduce muzzle rise by 30–40% (ammunition-dependent) via a unique angled port design. This component redirects barrel gases upward, counteracting muzzle climb and felt recoil to enable faster sight acquisition during rapid or continuous fire sequences. The primary problem it solves: managing the Reflex’s inherent snap in recoil impulse, particularly with defensive or +P loads, while minimizing trigger pinch caused by the slide cycling against the trigger finger between shots.

Compatibility

• FN Reflex (all barrel lengths)
• Direct thread-on to factory threaded barrel (1/2×28 TPI)
• Tested with SAAMI spec ammunition: light target rounds through +P duty loads
• Not recommended for hand loads below SAAMI pressure specifications

Key Features

• 30–40% muzzle rise reduction (confirmed with SAAMI spec ammunition)
• Angled gas ports redirect gases upward for recoil mitigation
• Wire EDM-cut integral clamp machined into the comp body – no thread locker required
• Clamp screws torque spec: 25 in-lb (do not exceed)
• Wings on comp body cover slide-to-comp gap for streamlined profile
• Reduces trigger pinch by keeping muzzle down between shots
• Tested with +P duty rounds; no malfunctions observed with SAAMI spec

Install Difficulty Rating: 2/5

Tools required: 1/16” hex key (provided), torque wrench capable of 25 in-lb (recommended). Install time: ~5 minutes. Thread comp onto barrel hand-tight, align ports, torque clamp screws to 25 in-lb. No thread locker – do not apply any compound to threads or clamping screws. Removal is reverse process.

FAQ

Will this work with my FN Reflex without modifying the barrel?

Yes. The MRAT threads directly onto the factory threaded barrel (1/2×28 TPI). No barrel modification or adapter is required. Ensure barrel threads are clean and dry before installation.

Why can’t I use thread locker on the clamp screws?

The integral clamp design is Wire EDM-cut to spec. Thread locker can interfere with the clamp’s mechanical grip and may cause screw seizure. The 25 in-lb torque spec provides sufficient retention without chemical aids.

Does this affect reliability with defensive ammunition?

No. The kit was tested with SAAMI spec +P duty rounds without malfunctions. Hand loads below SAAMI pressure may cause cycling issues. Use factory ammunition for best performance.
