How It Works

Minimum $500 Order




NOTE: We are a build to order manufacturer and all orders are built in the order in which they are received. Builds are estimated to take 3-4 weeks at this time.  

The Ultimate Assassin V2 has a few upgrades from our original Ultimate Assassin which was designed with input from our 3 gun team and other competitors. Minimal recoil, target transition at depth, and weight are their primary concerns. The Ultimate Assassin V2 is the billet counterpart to the Black Assassin V2 and has been recently upgraded with a crisp clean trigger and our R2 muzzle break. The R2 muzzle break is light, and significantly reduces muzzle lift and recoil. The competition rifle outshoots most of it’s users.
