Ready to piece together your own AR? Finished up your 80% lower or stripped lower and want to assemble your own upper receiver piece by piece? Start with quality: Grab one of our forged, mil-spec (7075-T6) "Flattop" stripped AR-15 upper receivers. This M4-type upper features a standard M1913/Picatinny rail and proper M4 feed ramps for utter reliability. It ships truly stripped (no forward assist or dust cover) allowing you to install your own custom components. With a perfect anodized coating, no T-marks and no obnoxious roll-marks or brand hallmarks, this upper receiver makes the perfect candidate for an M4 forgery or mil-spec clone build. It will match just about any stripped lower receiver, anodized handguard, and buffer tube of your choice.
