Aero Precision M4E1 Enhanced AR-15 Upper - No Forward Assist - Anodized Black

The Aero Precision M4E1 Enhanced AR-15 Stripped Upper is a one-piece forging that combines the handguard mounting hardware with the upper receiver. This design allows for additional lightening cuts, resulting in increased weight savings and improved cooling efficiency. The upper is made from a 7075-T6 aluminum forging machined to MIL-SPEC and finished with a durable hardcoat anodized finish. It is compatible with all MIL-SPEC AR-15/M16 components and removes the forward assist for further weight savings.

Note: This upper receiver is not compatible with piston kits.

It supports barrels up to 1" in diameter and features M4 feedramps, a black anodized finish, and is machined for .250” takedown/pivot pins.
