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

  • Handguard mounting platform is forged into the receiver

Great product at an affordable price Review by Bart

Placed my order on Monday morning, upper arrived on Friday (free shipping option). You can tell this upper is of really high quality just by holding it. Was set on buying a lower from a different very well known company but after seeing this upper I'm definitely going with an Aero Precision lower. Priced really well for what you are getting.

Top tier period!!!! Review by Mark

Purchased thru a dealer but figured I'd give a review anyways . I have bought many Ar products over the years . I always buy quality period !!! I've bought some of the best known top tier that is on anyone's "list" of top tier manufacturers. Aero precision has never left me regretting! Must add buying other BIG TOP TIER brands and paying up for their products makes me think I may have done just as well to go aero .im not saying the great brands let me down . Aero precision quality is just as good as the well known and might add expensive top tier products.ill always buy with confidence from aero .nothing I can add to the review that hasn't already been stated by others.

Very impressed with upper's quality and design Review by Charles

This is a step above of the other uppers I have used as far as it's design and the exceptional quality and finish. I have been satisfied with my standard AERO uppers so I thought I would try this unique design upper for my newest build using an 18" .223 Wylde SS Ballistic Advantage barrel. I'm positive by combining the ridgidity of this upper's design and the quality of the BA barrel, this will make my most accurate build...a key mod 12" full float handguard and VG6 Gamma muzzel break will finish it off when they arrive later this week. I highly recommend someone wanting an easy and strong barrel installment that offers an easy and strong floating handguard to give these a look.
AERO has a winner in this upper! (Posted on 7/11/2017)
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)
