AirMarksman Anvil Rail

16.25" ARCA. Cross-Hatched Grip. Balance-Optimized. Made in the USA.

The AirMarksman Anvil Rail is the first under-bottle ARCA rail designed specifically for the FX Impact — developed in collaboration with active NRL/PRS shooters to bring both full-length ARCA functionality and improved rifle balance to the Impact platform. With 16.25 inches of usable ARCA rail space extending forward under the bottle and rearward under the trigger, a cross-hatched grip surface, M-LOK compatible channel with pre-tapped 10-24 holes for weight customization, and a flat level surface under the natural balance point of the rifle — the Anvil Rail is the most comprehensive under-rail solution available for the FX Impact. Made in the USA.

Overview

The Anvil Rail addresses two common FX Impact platform challenges simultaneously — limited ARCA rail coverage and the back-heavy balance characteristic of the Impact design. The 2 lb rail itself adds meaningful forward weight to counteract the Impact's natural rearward balance bias, and the 16.25" ARCA surface centered under the natural balance point of the rifle creates a flat, level shooting platform on bags and barricades for improved stability. The cross-hatched underside of the ARCA rail adds grip friction when placed on bags and obstacles for more consistent, stable supported shooting.
