9MM AR9 Barrel 

Our 9mm barrels are a great place to start a 9mm conversion project for your AR15 or a from scratch build of an AR9.  9mm Luger ammunition operates well in an AR15 pistol or 16" 9mm AR15 rifle configuration.  A 9mm AR15 is a great plinking gun or first AR for a child that is inexpensive to shoot while still giving the AR experience.

AR15Parts.com barrels are sourced from top US manufacturers including Ballistic Advantage, Shaw Barrels, Swan Machine, Wilson Arms, Wilson Combat, ZRO Delta, and others.
