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.

Receiver is great! Fit and function perfect. Price was right and delivery outstanding.
Thank you!

Well made, and extra stout.

Got this upper for a precision rifle project, specifically to aid in the stiffness of a longer barrel. I believe it'll work well. The extra weight of the enhanced barrel mount is of no concern with a PRS setup.
