These makers emphasize testing prior to shipment for your satisfaction. CMMG conducts magnetic particle testing on its barrels, a process which reveals tiny flaws.

Get the Rifle You Really Want with AR-15 Upper Receiver Parts

Make a match rifle or a versatile hunting firearm with AR-15 upper receiver parts. The AR15’s modular structure allows you to modify its design to meet your aspirations. Find a flat top so you can reconfigure as needed. We carry an M4 version of the AR15 carbine – its flat top provides a range of sighting options. Many of our AR-15 upper receiver parts are made from higher grade, mil-spec steel and work with existing mil-spec lowers. We’re also your superlative source for AR 15 parts sold individually, from charging handle assemblies to sling mounts.

AR-15 Upper Receiver Assembly Ensures Components Coincide

When you want the complete package, we’re here with assemblies! You can opt for an AR-15 Upper Receiver Assembly featuring a 16-inch barrel and a 1:9 twist, paired with a flash suppressor, mount, bolt assembly and charging handle. A dedicated bolt to match the upper assembly is important to the workings of your AR-15. You’ll also benefit from a handle matched to your barrel. Choose AR-15 upper receiver assemblies backed by precision manufacturing to add to your rifle or when building a firearm from square one.
