AR-15 Upper Receivers

Find the Upper Receiver Parts You Need for your AR-15 Gun

Customize or begin building sooner with our AR-15 Upper Receivers. We have receivers boasting hard chrome-lined chambers and bores that deliver exceptional endurance and easier maintenance. Choose from a fast 1:7 twist or the popular 1:9 rate in our selection of AR-15 upper receivers. Top names in receiver manufacturing are here, including Rock River Arms, CMMG, and ArmaLite. These makers emphasize testing prior to shipment for your satisfaction. CMMG conducts magnetic particle testing on its barrels, a process which reveals tiny flaws. Order a Carbine Upper Receiver with M4 feed ramps and Bird Cage flash suppressor from this manufacturer.

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.
