The Aero Precision M4E1 Lower Receiver delivers billet aesthetics in a forged package. This enhanced forging is machined from 7075-T6 aluminum and compatible with all Mil-Spec AR-15 parts. A threaded bolt catch roll pin offers simpler installation of the bolt catch and virtually eliminates the possibility of damage to the receiver finish during installation (pin included). 1/16" Hex Key required for assembly. An integrated trigger guard eliminates the possibility of breaking the trigger guard tabs and an upper tension screw inserted in the grip tang of the lower receiver provides a fine tune adjustment for the fit of the upper and lower receiver.

Features:
  • Compatible with standard AR-15 components and magazines
  • Nylon tipped tensioning set screw
  • Threaded bolt catch roll pin (included)
  • Machined from 7075-T6 forged aluminum
  • Anodized black
  • Rear takedown pin detent hole is threaded for a 4-40 set screw
  • Weight: 8.61 oz

A threaded takedown pin detent recess allows easy installation of the takedown pin detent and spring with the use of a 4-40 set screw. Increased magwell flare aids in quick and efficient magazine changes. Marked and milled to accept short-throw safety selectors, but will work with standard selectors as well.

Aero Precision is known for superior engineering and machining. They push the boundaries of manufacturing and challenge the status quo by constantly looking for new ways to develop and evolve.

The Best Stuff!!

by -

These lowers are phenomenal! Just built a 556 with a 10.5 inch barrel. It came out way better than I expected. I would love to do another one and hopefully I will do so soon!

Amazing!

This lower is amazing! Took me no time to build. It was my first build (thank you youtube videos...) and it works great! Looking forward to go try it at the range on my AR15 pistol, as soon as I find ammo :-). I will definitely buy again...

Phenomenal receiver with great features

by -

This a solid lower with a pleasing look and some great features. Starting a pistol build and having the threaded pin for the bolt catch and the set screw for the rear take-down pin make this a cinch to build. Also, having the set screw to stiffen the lock-up between the upper and lower. Aero hit it out the park with these! Definitely will be using these in future builds!

High Quality

by -

Excellent machining, fit, finish. Easy to assemble. Large mag well flare. I personally like the styling. It is much nicer than my Anderson's in nearly every way. To me its worth the extra $ for most builds.

I'm sold on Aero Precision

by -

This was the first part I ordered for my 1st-ever AR build. I really didn't know too much about building a carbine, but I was fortunate to come across this product which happened to be in stock at the time. This turned out to be one of the best parts I purchased for my build. It's solid quality and it was a straightforward install. I have purchased additional Aero products as a result - highly recommended!
