Aero Precision TWO (2) M4E1 Threaded Stripped Upper Receivers (AR15) - Anodized Black (BLEM)
This lot includes two Aero Precision M4E1 Threaded Stripped Upper Receivers for AR15 builds. The M4E1 Threaded design uses an enhanced forging for a billet-style profile while retaining compatibility with standard AR15 barrel nuts and components.
These are factory BLEM units (cosmetic blemish); function/fit is expected to be within spec.
Each receiver is forged from 7075-T6 aluminum and finished in anodized black, with M4 feedramps, .250 takedown pin holes, and laser-engraved T-marks on the top Picatinny rail.
