Aero Precision M4E1 Threaded Assembled Receiver Set - Anodized Black

Aero Precision M4E1 Threaded Assembled Receiver Set – Anodized Black

Includes:

• M4E1 Lower Receiver in Anodized Black
• M4E1 Threaded Assembled Upper Receiver in Anodized Black

M4E1 Lower Receiver Features:

• Threaded Bolt Catch Roll Pin – Allows for simple bolt catch installation and virtually eliminates the chance of damage to the finish during installation (pin included).
• Integrated Trigger Guard – Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger, more rigid platform to build upon.
• Upper Tension Screw – Allows users to fine-tune the fit of the upper and lower receiver using a nylon-tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.
• Threaded Takedown Pin Detent Recess – Allows users to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw (no more launching detents across the room).
• Increased Magwell Flare – Increased the flare of the magwell to aid in quick and efficient magazine changes.

M4E1 Threaded Upper Receiver Features:

• New enhanced forging gives the upper receiver a “billet look.”
• New Picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
• M4 Feed ramps
• .250 takedown pin holes
• Laser engraved T-marks

Note:  Set may ship combined in one factory box, or in separate factory packaging.  Uppers and lowers are not mated, and the fit/function is identical regardless of packaging.
