Combat Armory AR-10 Stripped Upper Receiver Features The Combat Armory AR-10 Stripped Upper Receiver is machined from 7075-T6 aluminum billet a stronger and more consistent material than the forged or cast receivers found in some budget AR-10 builds. Built to Combat Armory s mil-spec tolerances the receiver is designed to accept standard AR-10 components without the fitment issues that can plague out-of-spec parts. Hard anodized feed ramps are machined directly into the receiver to promote smooth reliable cartridge feeding across the range of calibers available on the AR-10 platform. Finished in black the receiver matches the look of most mil-spec AR-10 builds and resists corrosion and wear over years of use. This upper is specifically built to fit DPMS Gen 1 pattern lowers making it a straightforward choice for builders working within that established ecosystem of parts and accessories. As a stripped upper it ships without a bolt carrier group charging handle or barrel giving builders full control over the rest of the components that go into their rifle. Combat Armory s machinists bring the same standards relied upon by military police and firearms enthusiasts to every receiver leaving their shop. The Combat Armory AR-10 Stripped Upper Receiver is available for sale at GrabAGun for builders assembling a DPMS Gen 1 pattern AR-10 rifle from the ground up.
