Has anyone faced an Aero M4E1 Enhanced upper?

If you mean truing, there should be no difference between doing on an M4E1 relative to any other. I tried a sans FA standard Aero a while back, along with shimming the barrel. Shoots better than me.

I’ve used Brownells tool on UR’s a few times. Didn’t seem to make much difference in accuracy; a 2 MOA Barrel was still a 2 MOA upper.
Barrel and ammo is where I go if looking for a legit Precision gun, but I completely understand the OC/Anal mindset.
I go there frequently.

Same experience here. I have the kit, but don't even check it anymore.

Well, the Enhanced version is not a std M4E1, hence why I was asking.

Front end is milled, all 1pc, etc.

I have no idea what the barrel/receiver interface looks like on Aero’s Enhanced uppers. Been a long time since I even saw them mentioned.

The Enhanced accepts std AR barrel extensions.

Like always, Pros & Cons. It takes the std hanguard mounting stress off of the barrel nut interface, and nut no longer needs to be timed for gas tube. However, Enhanced only accepts limited bigger/heavier handguards.

Never looked in to how those go together. Looks like it would be possible to do if the OD of the facing tool is smaller than the ID of the rail mount.

They are great from my sample of 1. My friend built a precision rig that performs great. This upper with their handguard and a rainier arms ultramatch barrel.

Its at least as good as my larue barrel in std reciever with giessle HG.

Any or the "bar" footprint handguards fit

Aero’s Enhanced uppers remind of me the old Mega MML uppers. Very solid platform, I expect the Aero stuff to perform similarly.

Thanks for link, good info.

I wonder if it's possible to machine the whole upper (receiver and handguard) as monolithic, but still allow a way to install barrel nut. M4E1 Enhanced has no interference with gas tube. Surely a monolithic takes away from the "modular" aspect, but perhaps it would just be for a small group of "pricision/accurate" shooters?

I just finished a build using an Aero lower and the Aero Enhanced M4E1 upper with a Compass Lake Douglas tactical contour barrel. This upper, as others have noted, has the extra mass of the independent handguard interface. The barrel took 12 weeks to arrive. I've got a Magpul UBR stock and Vltor buffer on it. I used a BCM parts kit for the lower, a Colt bolt and a Smith Enterprises Vortex flash suppressor. Barrel is bead blasted stainless at 20 inches in length, 1/7 twist and of course, rifle gas. The Aero Enhanced handguard fit and blended perfectly as did all the parts. The barrel fit tight and perfect and headspaced correctly. I had Compass Lake send a headspaced bolt also, and applaud their attention to detail. Aero Precision is a great choice based on my sample of one.

I installed an old Leupold 3.5-10x40, M3 from another AR15 with a Badger Comm 1 mount and total weight with a twenty round loaded mag is about 10.5 pounds. With the UBR collapsed overall length is 38 inches.

So how does it shoot?

I haven't had a chance to take it out. Busy days and poor weather, but I'll report back later when I get some ammo through it.

Roger.

We do ALOT of shooting in poor weather up here.

My friend used his as-produced, and its performing.

Reporting back. Function has been perfect with the Aero Precision rifle build. I've not chronographed any loads, but my old standard 55 gr. Sierra with 26.5 grs. of Winchester 748 produced .650 inch 5 shot groups at 100 yards. The 65 gr. Sierra and Speer 62 gr. both show good promise. Varget and 748 have produced the best groups. I wanted Tac to work, but so far no glory. The Hornady 75s are not working for this rifle. Next will be some 77 gr. class bullets.

Just curious, has this gun been assigned to a specific task?

Not really. I guess I was just going to see if a build could shoot any better than a Colt HBar Elite. The first 100 rounds shows that it will. My range is limited to 300 yards, but if I fix up portable targets I can move beyond my boundaries.

Yes, it is possible to lap the receiver face of the Aero M4E1 receiver. This company makes the appropriate lapping tool: https://www.x-caliber.net/bart-20?fbclid=IwAR0mxnmxIc8eP9DhUCizQuNTMOqk4O2eZZEi9Jim4KFu8SF0tnTOey3B0eg

There was another company (g and g rifle works) that also made a similar tool, but their website is no longer available so I have no idea if they are still in production.

I did an Aero M5E1 ("308" large frame upper) using the afore-mentioned X-caliber tool. The tool worked like it's supposed to. I know it's not exactly what you asked, being the large-frame AR instead of the M4E1, sorry. Figured it's kinda close.

I'm really late to this game, but, I check it on each and every upper. NO I don't use the Drill Powered tool. I built a tool years ago that is a fixture with .0001" TRO. I place the Upper on this jig, insert it in a 4 Jaw Chuck adjust of .0001 TRO at an indexing area just beyond the Barrel Stop Ring Mating Surface. Once "zeroed" i can now check Concentricity and Perpendicularity of the Receiver Flange to the Long Axis. Here's the important part, first I measure. To quote an old James Gang Tune "Garden Gate" - "The captain’s in the chartroom Navigating on a star, Can’t know where we’re going 'Cause he don’t know where we are" I also check the CL of the rail for Parallel to the Long Axis of the Receiver (both axis). It's surprising the number of Uppers that are off in this dimension. I guess the concept here is "they got windage and elevation adjustment". But, on a Billet????
As to the original question I have found big $$$ Billet uppers off of perpendicularity by .003". I have also found $39 Mil-Spec perfect.
