Description

Our state of the art M4E1 platform starts here, with the M4E1 Upper Receiver. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superior engineering, we have condensed the parts needed to mount a free-floated handguard to a mere 8 screws. Since the handguard mounting surface and upper are of the same forging, not only is it a stronger system, but we are able to make additional lightening cuts to save weight and allow for more efficient cooling.

Ease of installation - Simply insert your barrel assembly into the M4E1 upper, tighten it using the provided barrel nut and wrench, slide your rail on and tighten the rail screws. Within minutes you have a modular, free-floated rail.

Features:

  • M4 Feedramps
  • .250 takedown pin holes
  • Lazer engraved T-marks
  • Comes assembled, with dust cover and forward assist installed

M4E1 Specific Details:

  • Handguard mounting platform is forged into the receiver

Engineering Masterpiece Review by Eric

There's nothing else to say, other than the Enhanced setup makes a standard upper second rate. They need to rewrite the book with this being the norm. As far as I'm concerned, no other company is worth looking at for an upper/handguard. You literally cannot beat that design. (Posted on 11/20/2016)
Blem? - Where? Review by Keith

I just received this M4E1 blemish upper and spent 10 minutes looking for the blemish; can't see it except for a tiny scratch where the FA screw is. Great upper and great price. Can't wait to get this build finished. (Posted on 9/22/2016)
Well worth it Review by Christopher

This thing fits the Aero Lower like it was cut from the same piece of Aluninum. the hand guard once I put in place was just as solid as the monolithic AR builds I have held. Not having to index (clock) the gas tube made life so much easier as well. I hope that they bring back the M5E1 uppers soon as I will be building a creedmore soon. I would also Like to see if they can make an enhanced version of their .458 SOCOM upper. Heck all uppers should be the Aero enhanced line. Lovn it. (Posted on 9/8/2016)

Perfect Blem. Contradictory, I know, but true!
An amazing work of art. I shows how much time, dedication, and experience has gone into manufacturing these uppers. I only assume you are reading this deep into the reviews due to the fact that you waited to long to add the upper to your cart and now your on the email list for notifications when back in stock... Its ok nobody is perfect. *Note that I use my new M4E1 Upper as a gauge when measuring said perfection. You better set that email alert to your phone and be ready to strike when the moment is right thus allowing your AR build to rise like the phoenix from the ashes ready to smite all who should come against you! Great job guys. Aero'er for life (Posted on 7/20/2016)
I really like my lastest 300 BLK 16" upper Review by IntelMerc
Quality

Value
I got an enhanced M4E1 upper (blem) and a 15" Quantum Mlok handguard for such a good price, I decided to make myself a 16" 300BLK rifle. I'd been making 8 and 10" SBR/pistols before, but I needed something longer. There are arguably "cheaper or better" AR components from other companies, but as far as I'm concerned, Aero Precision is my only brand for AR builds.

I ordered a blem, but I couldn't initially tell where the flaw was. It turns out that the flaw was in the dust cover spring. I had a "too short" short leg what wouldn't hold tension. Whatever! I had a spare spring in a loose change cup in the kitchen.

So I matched the M4E1 and Quantum hanguard to a 16" Ballistic Advantage Modern Series barrel, BA nickel boron BCG, and a BCM Gunfighter MOD 1 - 7.62 / 300 Blackout Compensator. What I build isn't some $3k match grade rifle, and I ain't no sniper, but my latest rifle's accuracy is more than satisfying.

Caliber Swap Review by Paul
Quality

Just pulled off a caliber swap in less than 5 minutes!!! Not something I do on the regular, I normally just swap the whole upper when I want a different caliber or barrel length. However, this was the last time I was going to be shooting 6.5 Grendel for a while (do to unpopularity at local gun stores and shipping restrictions on ammo to certain cities in Kalifornia). Sure is nice to know that if I ever get my hands on that 6.5Grendel ammo, it's not a pain in the you know what to swap the barrels out again. Anyways, I'm a believer, and sticking with Aero Precision. (Posted on 6/26/2016)

I'm not even going to deduct a star for the banged up dust cover because this upper is simple astounding. (Posted on 6/25/2016)

Awesome product at a great price! Made assembling the upper for a15 ridiculously easy. No need to mess with shims! Also I love when paired with aero free float handguard the rail is continuous from the upper receiver to the handguard unlike other companies. Makes it look so much cleaner. Thanks Aero!

This enhanced upper made for a nice easy build. The Aero handguard choices are also well machined and precise fitting. I used a Quantum version handguard and couldn't be happier! (Posted on 5/26/2016)
Great Product, Very Pleased With My Purchase! Review by Christopher

I now have two of these uppers, and couldnt be more pleased with my purchase. They are both on custom AR builds, and i believe these provide for the best method of hand guard attachment, plus the gas tube routing and barrel nut attachments are wonderful too. I also have a standard uppen on one of my sons rifles as he insisted on a Troy Alpha hand guard. I use the two enhanced uppers with Aeros M-LOK BAR hand guards, which I also love. As with all Aero products, I am very happy with the quality and will be using the same parts again on my next build! (Posted on 4/24/2016)
