9MM UPPERS

Paired with an AR9 lower, our 9mm AR9/PCC upper assemblies give you the best of both worlds - the AR15 form factor and ease of use, with inexpensive 9mm Luger (9x19mm) ammunition. The 9mm upper assemblies can also be used with standard AR15 lowers by adding a Magwell adapter from Stern Defense or CMMG that accepts your existing 9mm magazines. A 9mm AR15/AR9 is a great first AR for you kids, a fun plinking gun, or a practice weapon - whatever your use, it will cost a lot less to shoot.

Any 9mm Upper Receiver we sell can be configured to your specifications before adding it to the cart.  We offer matched muzzle devices, rails, bolt carrier groups, magazines, and charging handles to make your 9mm Upper Assembly turn key and ready to shoot out of the box.

AR15Parts.com components are sourced from top US manufacturers including Aero Precision, Anderson Manufacturing, Ballistic Advantage, Shaw Barrels, Swan Machine, Wilson Arms, Wilson Combat, ZRO Delta, and others. Each upper assembly has options to select Rail, Muzzle Device, Bolt Carrier Group (BCG), Charging Handle, and Magazine. Additional parts are available individually on our website.
