AR15 / AR9 Barrel - 9mm 8.375" 1:10

Outerwild 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. 0ur quality control system ensures they are dimensionally correct and bores fall well within their individual tolerance ensuring superior accuracy. This barrel is designed to fit a 7" handguard (our Premium, Raven and Onyx handguards are the perfect compliment) with minimal gap between the handguard and a suppressor.
