Apex Tactical’s MRAT FNX 45 Compensator — Reduce Recoil and Climb

Apex Tactical Specialties, an Arizona-based accessories company, is now offering the MRAT FNX 45 compensator for FNX-45 pistols with factory threaded barrels.

Aftermarket options for the threaded FNX-45 pistol expanded with the Apex Tactical MRAT Compensator. The MRAT stands for Muzzle Rise Amplitude Tamer and is supposed to dramatically reduce felt recoil and muzzle rise.

The MRAT, or Muzzle Rise Amplitude Tamer, was designed to dramatically reduce both felt recoil and muzzle rise of the FNX-45 model pistols while shooting. The reduction is so significant, in fact, that Apex provides a captive-spring guide rod assembly to ensure proper function due to the reduced slide velocity produced by the MRAT.

Apex MRAT FNX 45 Compensator components
Included in the box from Apex for a reportedly easy install: the MRAT FNX 45 Compensator, a captive-spring guide rod assembly, two brass tip set screws, and a vial of thread locker fluid.

The MRAT was tested with a variety of SAAMI spec ammunition; from the lightest ‘target’ rounds to +P duty rounds. The result was a 40% to 60% reduction in muzzle rise, with Fiocchi 230gr FMJ giving 44% and Federal 230gr Personal Defense Punch JHP giving 67% reduction, according to Apex. The company did state that results may vary based on both the ammunition used and the individual shooter.

The kit contains the MRAT Compensator, a captive-spring guide rod assembly, two brass tip set screws, and a 1.8ml vial of thread locker fluid. The installation is easy, and Apex provides a detailed how-to video to properly guide customers through the process.

The MRAT comes in Black, which is in stock and available now is $175, or FDE, which has a small wait time and an MSRP of $200.
