AR15 M4E1 Enhanced Upper Receiver - Anodized Black Product Sku: APAR600201AC
$149.00
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
  • Compatible with Aero Precision Enhanced and Quantum Series handguards but also fits most BAR-system handguards
  • Barrel nut and wrench are included

I cannot say enough good things about Aero's Enhanced Uppers! I can only say that I will be getting another one. (Posted on 4/19/2018)
Nice design for the price Review by Chris R

For those who don't want to commit to a monolith. I use this with the 12" Quantum rail and it feels very solid. My only complaint is the last pair of screws were pretty hard to get in there because the holes didn't line up perfectly. Other than that my upper feels stout and makes a barrel swap a breeze.

Awesome upper Review by Matt

I bought this upper for my first AR build. This upper takes the guesswork out of installing a barrel. Finished this upper with 15" Quantum handguard. Plus this upper fits nice and tight with my Anderson lower. Aero customer service is great too. They instantly answered my questions over chat. Thanks Aero! (Posted on 1/18/2018)
Outstanding Review by Kim

Used this for my first .300 Blackout build. Made assembling the upper extremely easy. Used a Wilson Combat match barrel. Less that 0.5 MOA at 100 yrds. Awesome gun. The range officer tried it out and said that it was one of the best he'd shot. Next build is the M5 in .308. (Posted on 12/21/2017)
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.

I have two of these, one in Wilde and the other in .300 BO to go with my AP lower. The quality, fit, finish, and performance are great. (Posted on 7/19/2017)
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)
