Bring iconic field-proven camouflage into your modern AR-15 build with the Shark Coast Tactical M81 Woodland Rifle. Chambered in 5.56mm NATO and built around a battle-tested feature set, this rifle delivers dependable performance straight out of the box — whether you’re heading to the range, competing, or adding a distinctive pattern to your collection.

Built to Perform

At the heart of this rifle is a 16″ 4150 Chrome Moly Vanadium (CMV) Melonite-treated barrel with a 1:7 twist rate and M4 feed ramps for reliable feeding across a wide range of 5.56mm ammunition. The carbine-length gas system paired with a low-profile gas block delivers a smooth, consistent cycling experience, while the 1/2-28 threaded muzzle — capped with an A2 flash hider — keeps your options open for adding your preferred muzzle device.
