MRAT Compensator Kit for FNX-45

Description

The MRAT Compensator Kit for the FNX-45 is a complete, direct thread-on system engineered to deliver measurable performance improvements for your pistol. By reducing muzzle rise by 40-60% depending on your ammunition choice, this compensator helps you stay on target and get back on the front sight faster after each shot. That means more accurate follow-up rounds and less perceived recoil, making range time more productive and comfortable.

This kit is not a standalone compensator. It includes a captive-spring guide rod assembly that is required for proper function. The MRAT reduces slide velocity during cycling, and the included guide rod compensates for that change to keep the action running reliably. The spring retaining nut is removable, allowing you to swap out the spring for additional tuning if you want to fine-tune the system for your preferred load. This is a practical upgrade for shooters who want to reduce muzzle flip without sacrificing the reliability of their FNX-45.

The compensator body features integrated wings that bridge the gap between the slide and the comp, giving the pistol a streamlined, finished appearance. It is not just functional—the design also provides a custom look that stands out from standard factory configurations. The kit was tested extensively with SAAMI spec ammunition, from light target loads up to +P duty rounds. Hand loads that fall below SAAMI pressure specifications may cause malfunctions, so stick with factory ammunition for best results.
