Enhanced Strength & Looks of Billet - Accepts Mil-Spec Parts & Accessories
Aero Precision’s M4E1 Threaded Assembled Upper Receiver gives you the best of two worlds: that badass looks and robustness of a billet receiver plus the easy parts compatibility (and price!) of a traditional mil-spec upper. And it comes with two nit-picky jobs done for you: the forward assist and ejection port cover are already installed. But there’s more...
The M4E1 Threaded Assembled Upper Receiver is Aero Precision’s M4E1 Enhanced Upper with standard barrel threads up front so it can accept a standard AR-15 barrel nut and handguard attachment. The original M4E1 upper is configured for the proprietary attachment system Aero’s Gen 2 Enhanced or Atlas ’guards. This version gives you all the M4E1 upper features and lets you build your rifle with a different handguard. It’s ready to serve as the foundation of an exciting custom AR-15.
- Hardcoat anodized finish, matte black
- Laser-engraved T marks on the Picatinny top rail
- M4-type feed ramps
- .250" takedown pin holes
- Also available "stripped" - without forward assist & ejection port cover (#100-026-237)
The Aero Precision M4E1 Threaded Assembled Upper Receiver is forged from 7075 T6 aluminum, like a regular mil-spec receiver, but with angular external contours that add the strength - and custom look - of a "billet" receiver. It accepts any mil-spec AR-15 bolt/carrier group (not included) and fits on a standard AR-15 lower - though it looks darned good paired up with Aero’s equally rugged, all-business M4E1 forged lower receiver.

Free-Float Aluminum Handguard Ready for M-LOK? Accessories
Bravo Company’s BCM MCMR M-LOK® Compatible Modular Rail handguard gives you a full-length topside Picatinny and seven rows of M-LOK® slots to ensure you have vast expanse of room for mounting accessories. Engineered to minimize bulk, the MCMR is essentially Bravo Company’s popular KMR handguard adapted for the M-LOK® accessory mounting system originally developed by Magpul.
The MCMR M-LOK® Compatible Modular Rail handguard gives you a streamlined, clean-looking rifle that is also easy to grasp and maneuver. The MCMR free-floats your barrel, so the weight of the handguard and attached accessories won’t compromise the gun’s accuracy.
- Engineered for exceptional cross-sectional strength
- Available in a variety of lengths to fit your rifle & suit your needs
- Top Picatinny rail is T-marked
- INCLUDES Proprietary steel barrel nut (same one used on BCM KMR, MCMR and QRF handguards) & installation instructions
The BCM MMR M-LOK ® Compatible Modular Rail handguard is fully dehorned so there are no sharp edges to bite into your hand or snag on your gear. It’s machined from 6061 T6 aluminum for the optimum balance of strength vs. weight, then given a hardcoat anodized finish for extra surface strength and corrosion resistance (yes, aluminum will corrode - look at an older car with factory alloy wheels!).
