Aero Precision M4E1 5.56 NATO No Forward Assist Enhanced Upper Receiver

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.
