The TYPE 15 is a combination of billet precision and military heritage. The receiver set is machined from high-grade 7075-T6511 billet aluminum for the tightest tolerances to secure a wobble-free fitment and to prevent dust and debris from entering. Assembled with an ambidextrous charging handle and WATCHTOWER's patented safety selector to satisfy the need for more dexterity, which allows more surface area to manipulate the mechanics of the firearm. We've also upgraded the fire control group with Hiperfire's EDT2 Heavy Gunner trigger. A single-stage semi-auto LE/SWAT AR upgrade. The TYPE 15 includes our Tru-Black PVD coated 5.56 NATO M16 profile MPI tested Durabolt BCG, our most robust, durable, and easy-to-clean coating. Choose either a 10.5-inch 5.56 NATO cold hammer forged or .223 Wylde stainless steel barrel with a 1:8 rifling twist and has a mid-length gas system. Surrounding the barrel is the 10-inch S7M free-floating handguard with M-LOK attachment slots at five positions, 4 QD points, and a full-length 1913 Picatinny rail. WATCHTOWER's Flat Face compensating muzzle brake is incorporated at the end of the barrel, a device to mitigate recoil, finished in a Tru-black PVD coating. This rifle also comes with B5 Systems reinforced polymer pistol grip.
