The Aero Precision M4E1 Enhanced AR-15 Stripped Upper without forward assist incorporates the handguard mounting hardware with the upper receiver into a single forging. Increased weight savings and improved cooling efficiency are made possible by additional lightening cuts afforded by this stronger one-piece design. Crafted from a 7075-T6 aluminum forging machined to MIL-SPEC, the upper is then finished in a durable flat dark earth Cerakote. Compatible with all MIL-SPEC AR-15/M16 components. For even further weight savings, this model removes the often unnecessary forward assist.
Installation is a breeze. Simply insert your barrel assembly into the M4E1 upper then tighten it using the provided barrel nut and wrench. Next, slide your rail on and tighten down the rail screws. Within minutes you have an assembled upper receiver.
NOTE: Compatible with Aero Precision Enhanced and Quantum Series handguards. Also fits most BAR-system handguards. Barrel nut and wrench are included. This upper receiver is not piston-kit compatible. Supports barrels up to 1" in diameter.
