Description
For Florida shooters, the combination of humidity, salt air, and daily carry demands gear that performs without compromise. The MRAT Compensator for the FN Reflex is built for that reality. At $140, this is a direct thread-on compensator that measurably reduces muzzle rise by 30-40% depending on the ammunition you feed it. That’s not marketing — that’s a hard number from real testing.
The key is the unique angled port design. It redirects barrel gases upward, pulling the muzzle back down between shots. The result is faster sight acquisition during follow-up shots, less felt recoil, and a noticeably smoother shooting experience. Our testers also reported a reduction in “trigger pinch” after each round — less snappy muzzle rise means your trigger finger stays comfortable through an entire range session. More control, more fun.
Mounting is straightforward and secure. The MRAT uses a built-in clamp that is Wire EDM cut into the profile of the compensator. This allows fast installation and removal without thread locker compounds. No messy cleanup, no stuck parts. 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 misaligning — a common issue with other screw-clamp designs. Torque the screws to 25 in-lb. Do not use thread locker on the MRAT threads or clamping screws.
This compensator was tested with a wide range of SAAMI spec ammunition, from light target rounds to +P duty loads. For daily carry or defensive use, it runs reliably. If you hand-load rounds below SAAMI spec pressure, you may experience malfunctions — stick to factory ammunition for consistent performance.
The wings on the compensator body cover the gap between the slide and comp, giving the pistol a streamlined, integrated look. It doesn’t add unnecessary bulk, and the corrosion-resistant finish holds up to Florida’s coastal conditions — sweat, sea air, and humidity won’t compromise it.
