Aero Precision M4E1 Enhanced Upper Receiver

[UWone77]

Not too long ago, we previewed the new Aero Precision Rail. To go along with the new rail, Aero Precision is also releasing their Enhanced Upper Receiver to match up with their new Rail. I understand the new rail will also be available separately as a version to attach to standard upper receivers. As I posted in the rail thread, lengths available will be 7,9,12,13, and 15". The Rail will have an inner diameter of 1.75" to accommodate most suppressors.

Now that Aero Precision (http://aeroprecisionusa.com/m4e1) has released the complete specs and details of their M4E1 Enhanced Upper Receiver, we've updated this post.


Description:


The AR15 weapon system is an ever-evolving and modular platform. That weapon system has now been enhanced by Aero Precision into the new M4E1 platform. The M4E1 upper receiver is precision-machined to our specifications and features M4 feed ramps and handguard mounting platform. The rail mounting surface and barrel nut area provide a much stiffer system than a standard receiver, giving you more accuracy out of your rifle. Lightweight by design, stronger through superior engineering, the M4E1 delivers monolithic accuracy in a lightweight package.


Features:


Forged from 7075 T6 aluminum
Precision machined to M4E1 specs
M4 feedramps
Matte black hard coat anodized Mil 8625 Type 3 Class 2 or Cerakote coating
.250" takedown pin holes
Laser engraved T-marks
Accepts standard AR15/M16 components
Handguard mounting platform is forged into the receiver
Works with Aero Precision handguards but also fits most BAR-system handguards
Comes assembled, with dust cover and forward assist installed
Barrel nut and wrench are included


M4E1 Upper Receiver


It all begins with our all new state-of-the-art forged upper receiver. The M4E1 upper receiver is a one-piece design combining the rail's mounting surface with the upper itself.

Lighter design, stronger product
By machining the rail's mounting surface into the upper itself we have condensed the parts needed to mount a free-floated rail to a mere 8 screws. Since it is of the same forging as the upper not only is it a stronger system, but we are able to make even more lightening cuts to save weight and allow for more efficient cooling.

Ease of rail and barrel 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.

Near seamless rail & upper alignment
This design removes the human element margin of error when it comes to not only installation, but also correct alignment and removing any gap between the upper and the rail.


M4E1 Rails


Choose a rail length and design that matches your shooting style. With how quickly rails can be changed out, we won't blame you if you get two. Plus, our Enhanced Rails are wide enough to fit your suppressor under them - perfect for a short barrel suppressor package.

Enhanced Quad Rail
For the traditional tactician that needs the rail real estate for their tools of trade, or for those that prefer the feel and thickness of a full size handguard, the Enhanced Quad Rail models are for you. Available in 7", 9", 12", 13", and 15" lengths.

Enhanced Keymod Rail
With the absence of full time picatinny rails you get a slimmer profile, significant weight savings, and the freedom of adding accessories how and where you need them. Available in 7", 9", 12", 13", and 15" lengths.

Enhanced M-LOK Rail
If you lean towards Magpul product you will most likely be switching at least one of your carbines over to their new M-LOK system. The Enhanced M-LOK Rail will be ready soon, shortly followed by a launch of accessories from Magpul. Available in 7", 9", 12", 13", and 15" lengths.

The keymod rail looks really good.

[UWone77]

Looks like Aero Precision's Enhanced uppers/Rails are coming along nicely. They've posted that $300 will be the most expensive these get for the 15" Rail and Upper.

definitely a game changer, Aeroprecision is making a name for itself!! glad I found that company way before all their current production items. lol

[Naytwan]

Those look pretty sick. I'll have to pick one up.

I don't know about being a game changer.

Looks like a Seekins BAR rail with a Mega MKM Upper.

I was more referring to the integrated rail nut, which then again, kind of reminds of the of the Mega ones (or was it seekins?)

[Computalotapus]

Aero is my go to for quality low cost forged receivers that I know i will cerakote

[Computalotapus]

Also the wife says they have great customer service :)

[KevinBLC]

I think Seekins and Mega both have uppers that look like that. I'm not sure what they call it, but some kind of extension from the upper that mates up with the rail.

Mega MKM Maten is the one you are thinking about.

[UWone77]

Looks like Aero Precision is calling this their M4E1 Upper. Pre-sales have already started.

If that keymod upper is $300 or less that will be a pretty sick deal.

[mustangfreek]

Maybe the shorter rails, but i guess they will be a little more then that for the longer models

Not bad looking in the keymod version.

[HeavyDuty]

I was surprised to see a 12" Keymod and upper was about $275, so maybe not.

Well thats a decent price if the upper is complete (FA and DC kit) along with the barrel nut and wrench..

[GOST]

An enhanced 13" rail and upper Cerakoted is $322.15, that's going to be hard to beat.

[UWone77]

Original post has been updated with full release information and specifications.

Pre-sale units will be 5% less. They will be shipping at the end of May for anodized parts, June if you wanted cerakote.

Prices appear to range from $232.90 for a basic anodized one with a 7" Rail to $343.40 for a cerakoted upper and matching 15" M-LOK Rail.

They do, but it doesnt count towards this setup as they its already at 5% off ..bummer too as it probably would of pushed me over the edge and bought one.

[GOST]

Don't you hate getting pushed over the edge.[:D]

[UWone77]

I've got a 15" Quad coming, let's see how this looks.

[KevinBLC]

The more I look at it the more I like it. So they took a few ques from Mega and Seekins, but that price!!

[Calico Jack]

I have got a upper, 13" rail,16" barrel, and a bolt inbound. Can't wait! But I still have to buy the gas block and flash hider.

[GOST]

What brakes are you considering?

[Calico Jack]

For my needs a standard bird cage maybe fine or at least I believe so. But I am clueless when it comes to flash suppressors and muzzle. I plan to use the rifle if I get the opportunity to take some tactics classes and just target shooting.

[Naytwan]

I ordering the 13" keymod. I'm planning on doing a 14.5" barrel going to pick up an adjustable gas block for parallax tactical. Not sure what muzzle device I want. Leaning toward a battle comp or surefire.

[UWone77]

In keeping with their upcoming .308 theme, they will also be launching the M5E1, which is the .308 version of this enhanced upper for those waiting for that version. Looks like those will be available in just another 3-4 weeks.

[UWone77]

Aero Precision released a picture of their 9" M4E1 Upper on a 10.5" Barrel.

[GOST]

That upper is so tough it'll climb rocks.

[Calico Jack]

I got really happy when I got my shipping notice from Aero only to realize when the box arrived that it was just the bolt and barrel. I just the couldn't keep that end of May first week of June shipping schedule.

[GOST]

I hate it when you think you're getting your full order only to get part of it, makes my menstrual cycle start.

[Naytwan]

I emailed Aero and this is what I got back.


We are still waiting to receive the 13” KeyMod handguards. We are expecting them next week and I have made sure your order will be one of the first to go out when we get those handguards. I apologize for the delay on this. If you need anything else, please let me know.

Thank you and have a great day!

I do appreciate the communication. They got back to me very quickly. I will definitely be buying more stuff from them in the future. Its cool though cause now I have more time to figure out what barrel I want :)

Nice, I'm looking at the 13 or 15" KeyMod handguards myself, perhaps I'll change my mind to MLOK. Please post pics when you get it. They look great in pictures, but I'm curious to see what people's first hand opinion on them are.

Will do. I plan on doing a review once I build the rifle. I went with one of the joe bob outfitters barrels, griffin brake and I am looking for a gas block. Im thinking of a parallax tactical adjustable gas block. Hopefully I should have the rifle completed minus optic in 2 weeks :) That of course depends on Aero.

[Naytwan]

My upper came today. Very impressed. I'll do a review once I finish building it.

[GOST]

Nice to hear, will be waiting on your review.

[Calico Jack]

I am 90% done with my set up. I have to buy a bigger bench vise to torque the barrel nut down. Installing the pin block was teh scariest part since I do not have a drill press. I almost messed that up.

I was nervous dimpling my barrel. I finished mine. I am rocking Daniel Defense Irons on it for now. I am going to wait for the new Primary Arms red dot to put on it and I still need my grip wrap so I can run featureless. I am behind enemy lines after all. It has a raddlock maglock till then. Sorry for the crappy cellphone pic. I plan to take it to the range tomorrow to get a baseline zero and make sure everything works. I'm going to also take it out this weekend to a longer range to finalize my zero and have some fun. I'll post a review thread in the user review forum once I do.

That's a good looking upper!

[ennbee15]

Good looking upper. I may have to pick one up for a new build.

[Sak007]

Ant chance of one of this with no forward assist ? Or even better a lefty :P

[Turrican]

I have been using Aero receivers on my builds for a long time. Ive always been impressed with their ability to deliver great parts that are always in spec (unlike a lot of higher priced brand) for a fair price. they seem to be really coming out with some great stuff lately. I picked up one of their extended scope mounts and the thing was perfect for a rifle that didn't need a quick detach like the one I was building and the price was great. I am going to go now and order one of these to start a new build that I had absolutely no need for before seeing this thread.
