ATI FXH-45 Picatinny Rail For Inside Filler Plate on Top Slide

The ATI FXH-45 Picatinny Rail For Inside Filler Plate on Top Slide is a precision-engineered optic mounting solution purpose-built for American Tactical's FXH-45 and FXH-45 Moxie 1911 handgun platforms. This accessory fills a critical gap in modern tactical 1911 setups, enabling shooters to mount contemporary optics—red dots, reflex sights, or low-power variables—onto slides designed with internal rail geometry.

Manufactured from 1018 steel in Summerville, South Carolina, the ATI Picatinny rail features a parkerized finish that matches the slide's protective coating, ensuring corrosion resistance and aesthetic cohesion. The rail integrates with the FXH-45's interior filler plate design, allowing low-profile mounting that maintains slide integrity and doesn't require permanent alterations.

Law enforcement and competitive shooters benefit most from this upgrade, as sight radius extension and rapid target acquisition under stress rely on optic reliability and zero retention. The Picatinny standard ensures compatibility with any MIL-STD-1913 optic mount or adapter, providing flexibility to pair this rail with popular micro red dots like the Trijicon RMR, Holosun EPS, or Leupold DPP without additional hardware.
