AR15 16" Pencil Barrel - 5.56 NATO, Mid-Length, 1:7 Twist, Nitride

Introducing our new 16” mid-length pencil profile barrel, perfect for your lightweight build! Outerwild AR15 barrels are produced in-house by Outerwild. Using our fully automated robotic-driven production line, we drill, ream, rifle, contour and assemble our barrels from raw bar stock to the finished product. These barrels are properly stress relieved after rifling, air-gauge tested, and individually checked for head space. Our quality control system ensures they are dimensionally correct, and bores fall well within their individual tolerance ensuring superior accuracy.
