The McMillan DARPA XM-3 Rifle Stock (A1-3) replicates the original XM3 sniper system developed by DARPA in collaboration with Iron Brigade Armory. This stock features a drop in ready precision inlet for a Remington 700 Short Action, Badger M4 hinged floor plate, and Hart XM-3 barrel contour—no bedding or modification required. *Rifle Components, Lug, Barrel, EFR Mount and Bottom Metal are not included.
Built on the A1-3 design, this stock offers tactical versatility in a streamlined package. It includes an inlet for the XM3 Embedded Front Rail (EFR) for night vision mounting systems, staying true to its DARPA XM-3 rifle origins.
Constructed from durable fiberglass with sniper fill, the XM3 stock features machined-in aluminum pillars and a molded-in Olive finish.
Weighing in at approximately 3 lbs. 8 oz., this stock is significantly lighter than other tactical models, while still offering essential adjustability with a spacer system and 1/2″ Decelerator pad, giving a customizable length of pull from 13” to 14.5”.
⚠️ Note: This stock cannot be returned for fitment issues unless directly related to the specified action, barrel, or bottom metal. McMillan does not offer additional inletting or modifications for this product.
⚠️Note: Utility-grade Finish – mold lines, sanding marks, fiberglass cloth and small imperfections will be visible.
