AR15 AERO PRECISION M4E1 type rifle black barrel 14.5 '' cal. 5.56mm Black / FDE

M4E1 LOWER RECEIVER FEATURES:

• Threaded Breech Lock Pin - Allows for simple breech lock installation and virtually eliminates the risk of damaging 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 body, creating a stronger, more rigid platform.
• Top Tension Screw - Allows users to fine-tune the fit of the top and bottom using a nylon tension screw inserted into the tang of the bottom handle. This allows for a tight fit with any standard AR15 upper receiver.
• Threaded Housing for Locking Pin Detachment - Allows user to easily install the locking pin detachment and spring using a 4-40 set screw (no more cranking of detachments across the room).
• Increased Magwell Flare - Increased magazine well flare to facilitate quick and efficient magazine changes.

M4E1 THREADED UPPER RECEIVER FEATURES:

• New improved forging that gives the upper part of the receiver a "billet look"
• New picatinny profile that integrates perfectly with our Enhanced and ATLAS series hand guides.
• M4 feed ramp
• .250 takedown pin holes
• Laser engraved T marks

M-Lok Atlas R One handguard:

The ATLAS R-ONE is the latest addition to the Aero Precision handguard range. Machined from 6061-T6 aluminum, the R-ONE guardrail line is designed with size and weight in mind, providing the perfect guardrail for your lightweight construction.

ATLAS
The new Aero Taper Lock (ATLAS) mounting system is both functional and aesthetic. It features two conical, reflective locking nuts that provide evenly distributed clamping pressure on a custom-designed barrel nut, using a pan head screw. A ratchet detent further secures the design while ensuring positive registration during installation. By design, the uniform pressure of the ATLAS system avoids handguard deformation often observed with current applications during installation.
