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.
