Aero Precision’s new Aero Precision M4E1 Threaded Upper Receiver (formerly known as the Gen 2 Upper receiver) gives you that angled billet look without the high cost or the fitment issues many builders experience when trying to mate a non-matching billet upper/lower receiver. Aero precision has machined this stripped upper to accept a standard AR-15 barrel nut and mil-spec upper parts (Forward Assist & Dust Cover not included).
- New enhanced forging that gives the upper receiver a “billet look”
- Includes Threaded Roll Pin for ease of forward assist installation.
- M4 Feedramps
- .250 takedown pin holes
- Lazer engraved T-marks
- AR-15 Stripped Upper Receiver, Gen 2 in Anodized Black
Note: DOES NOT include port door and forward assist. If you would like these items pre-installed, select our AR-15 Gen 2 Assembled Upper Receiver.
