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

Can't go wrong with this Review by Mark

Installation of barrel and gas tube is the easiest with this upper. I thought the torque spec was a little high (50 ft. lbs.) while most other manufacturers go with 35-40 ft. lbs. but then again this isn't your typical mil-spec design. Put some anti-seize compound on the threads, torque and you're done. I love the fact that Aero Precision took the time to design an upper to increase accuracy. Good job guys. (Posted on 5/27/2017)
Picked up one on sale Review by Frederick

The M4E upper and 7" keymod free float rail is seriously high quality. The fit and finish was absolutely superb. Used a Daniel Defense lower parts kit with perfect fit. Already built another with the FDE for a friend and building another for my roommate. I cannot stress how great a value these are. Built several other AR's using Spike's Tactical, which is also high quality, but they don't compare against the enhanced free float handguard and the enhanced upper receiver. (Posted on 5/20/2017)
Great Upper Review by James

This is my first AeroPrecision Enhanced upper for a 300 Blackout pistol build, I also got the 9" Mlok handguard. The fit and finish is great, (it was supposedly a blem- I cant find one!!!) weight is perfect for pistol or SBR. I will definitely use the M4 & M5 Enhanced uppers in future builds. The tax man will enjoy my SBR & Suppressor applications. 3 day shipping is Great, don't waste your money and time in Orem Utah. No Chinese knock-off junk here!!! (Posted on 3/24/2017)

I have to say this is a fantastic design! The easiest platform for barrel assembly, and the fit and finish is perfect! I coupled it with an Aero lower and there is hardly any play! I couldn't be happier with the quality. (Posted on 3/7/2017)

The best upper money can buy! Review by Andrew

Bought one of these and a 7" quantum rail for my .300bo sbr build and I have to say the upper is flawless. The barrel slides in smoothly while still staying nice and tight. Handguard installation is a breeze with zero work trying to time a barrel nut. I'll be using these uppers for all my future builds. (Posted on 1/27/2017)
Simple and Solid Review by Andy

Bought a blemished one of these a few months ago for a 300 blk sbr. These make assembling uppers a breeze. No timing the barrel nut, no funky handguard mounts, just screw everything together. I've only put around 200 rounds through the assembled gun but the upper is holding up well. If you're looking at the blemished ones (if they're in stock) mine had some flow lines in the anodizing that you'll only notice if you're looking for it. Don't hesitate, they're good to go.

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)
