With its 18-in. match-grade, cerakoted, stainless steel barrel at the heart of its design, the M15TAC18 blends rugged durability with exacting precision. The Tactical handguard's slim, octagonal profile sports a full length MIL-STD 1913 12 o'clock rail for sights and accessories. 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.
