Stern 9mm barrels are ideal for gun lovers who want to build their own custom dedicated 9mm  AR15 upper group. Our barrels offer an advantage over the competition.  Every stern defense barrel throat is machined deeper for a longer free bore to accommodate bullets with a longer ogive.  We have found, some common defense rounds jam into the rifling before the round is fully chambered. Some of the barrels on the market do not accommodate this and can and will potentially result in nasty malfunctions resulting in a round being stuck in the chamber either requiring firing to clear or manual methods.

Note: Barrel comes with locating pin installed.
