The MRAT Compensator for the FNX-45 is a Direct Thread-on compensator that reduces muzzle rise by 40-60% (depending on ammunition).

A captive-spring guide rod assembly is included, which is necessary for proper function due to the reduced slide velocity produced by the MRAT. The spring retaining nut is removable to allow for spring replacement and additional tuning.

This kit was tested with a variety of SAAMI Spec ammunition; from the lightest "target" rounds to +P duty rounds. Hand loads with less than SAAMI Spec pressure may induce malfunctions.

- Reduced felt recoil

- Reduced muzzle rise

- Faster sight return after each round fired

- Wings on the comp body cover the gap between the slide and comp to provide a streamlined look

- Sweet custom look that nobody else has

- Note: FDE finish color is currently Cerakote Magpul FDE H-267.

For Use In These Guns

For use with FNX-45 Tactical and FNP-45 pistols equipped with a factory threaded barrel

Does Not Fit These Guns

FN 545 Tactical

FN 510 Tactical

The thread stickout of the 545 and 510 are much shorter than on the FNX-45 Tactical models, so our compensator will not fit or work properly.  Fear not, Apex is on it.
