ACE Hammer Buttstock, World’s strongest AR stock, machined from heat-treated aircraft aluminum. Laser etched position marks with a 7 position tube to ensure the perfect fit. Five spring loaded ball bearings ensure smooth tube transitions and a locking adjustment trigger. Also features an adjustable cheek rest and strike plate.
The ACE Hammer M4 collapsible butt stock was designed with input from special operations soldiers. ACE claims the stock is the strongest AR 15 series stock in the world because it dispenses with the polymer found in today’s designs and uses an all aluminum frame contoured for use against doors, windows or opponents in close quarter battles. It’s adjustable to seven positions, provided by a lockable lever, and the design also features an adjustable aluminum cheek piece and roller bearings which eliminate rattle when running. Additionally, four sling mount positions are provided.
