A tactical workhorse, the AR10TAC18 is the perfect tool for duty and defense. All Tactical Series rifles include Magpul MBUS flip-up sights and MOE + pistol grips. The dual purpose, flash hiding compensator tames recoil while reducing signature. A sturdy 15" key mod handguard provides ample hand space and a full length MIL-STD 1913 12 o'clock rail for sights and accessories. This model has an 18" black cerakoted stainless steel barrel, and a rifle-length gas system with an adjustable gas block. It features a Magpul STR multi-position collapsible buttstock.
