Originally developed as the Magpul Masada, the design was licensed by Remington Arms and Bushmaster, the former marketing a selective fire model for police, military and export sale and the latter producing a semi-automatic model for the domestic sporting market. Fitted with a birdcage flash hider on a 5.56 chambered 1/9 twist barrel, hand-adjustable gas piston system, reversible cocking handle, ambidextrous bolt catch, magazine catch and safety switch, free-float forearm, textured grip surfaces, and a side-folding adjustable buttstock. Mounted accessories include a Magpul MOE 1 3/4 inch rail segment on the forearm and a pair of Magpul back-up iron sights on the top rail. Magazine not included.

Excellent, with 98% of the original black finish, showing mild scuffs and handling marks. Mechanically excellent, with consignor notes stating that the rifle was upgraded per the 2010 Bushmaster factory recall on the ACR.
