The threaded barrel allows for standard muzzle accessories to be installed. Handguard is free-floated for accuracy and the slim 15" length provides enhanced ergonomics. Lower receiver is fitted with Magpul MOE grip and MOE SL collapsible buttstock on a Mil-Spec buffer tube. Includes a 30-round Magpul PMAG magazine.
