The White Oak Armament SPR AR15 Barrels are based on the Army's Squad Designated Marksman (SDM) Rifle Development Program, tasked with improving the accuracy of the standard issue rifle against targets out to 600 meters.

We offer these barrels to tactical users or casual shooters interested in the ability to hit distant targets with issued or mag length ammunition. These 18” barrels were developed for airborne troops. The .223/5.56 Wylde chamber gives excellent performance and reliability with a wide variety of ammo. The barrels also feature M4 feed ramps for reliable feeding.

Light weight contour results in a total weight of 41 oz. The muzzle is threaded ½ X 28 to accept a flash hider or muzzle brake. Select either mid or rifle-length gas system above.
