The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. It is machined from 7075-T6 aluminum with, M4 feedramps, .250 takedown pin holes, and supports barrels with a diameter up to 1". Included is a barrel nut and wrench, port door, and forward assist. This model has a black hardcoat anodized finish. NOTE: This upper is not piston-kit compatible.

Aero Precision’s roots are deeply tied to aerospace, and our drive for clean, perfect engineering and machining stems from that. When you’re building something that will fly in the air, there is no margin for error. We take that same approach in the firearms industry. Not every manufacturer will have razor thin tolerance levels. Not every manufacturer will personally oversee the development, design and machining of every part that comes off the line. We’re not every manufacturer.
