FN 15 Tactical.

The FN 15® Tactical .300 BLK II, chambered in the popular.300 AAC Blackout (7.62x35mm) cartridge, is duty-ready straight out of the box. Equipped with the FN Rail System, the carbine provides exceptional strength and durability over conventional systems and offers a stronger, more rigid platform for accessories and optics that will maintain their true zero, regardless of any impact to the carbine during fire. Additionally, the FN 15® Tactical Carbine .300 BLK II, like its rifle and carbine siblings, features a 16-inch, alloy-steel, cold hammer-forged and chrome-lined barrel, carbine-length gas system, low-profile gas block, SureFire ProComp muzzle break and Magpul MOE® furniture.
