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
Works with Aero Precision handguards but also fits most BAR-system handguards
Barrel nut and wrench are included
These uppers are not piston-kit compatible
Includes:
AR15 M4E1 Upper Receiver in Anodized Black
Port Door and Forward Assist installed
Barrel nut
Barrel nut wrench
do these only fit M4E1 lowers or will it fit gen 2 or standard lowers?
Hey on that aero precision upper how can you change the dust cover? Is there a way to take the one off to install a strike industries dust cover? Thanks.
That's not a integrated barrel nut. That's just made so you can only use bars style handguards. It makes it no easier than any other ar15 build.
I’m seriously loving the use of setscrews instead of those pesky roll pins. From an engineering perspective I can see how they extend the receiver life by preventing rotational wear. The modular construction is also an excellent advancement, making timing a thing of the past. I just received mine today with a 16” m4 profile barrel and 12” quantum mlok handguard. Absolutely rock solid and the most inexpensive free floated upper I’ve ever owned. I’m now a loyal Aero guy!
Are there any handguards out there that are compatible with that particular upper receiver. I just purchased one and want a longer handguard.
How much do they weigh vs a standard upper?
Ya'll are the first vid to show me clearly how to install my aftermarket barrel into the enhanced upper/handguard combo. Great vid!
So simple, just have to have money lots and lots of money lol. Great video. I like the Enhanced upper but can you only run Enhanced hand guards on it?
Great videos just wondering if you should put lock tight on barrel but?
I work across the parking lot from Aero they show alot of love when we buy any parts.
What is that little set screw by your thumb at frame 1:45
Two questions…
1) can you use an upper vice blocks on these "billet looking" forged uppers?
2) can you remove the dust covers on these uppers…by removing the c-clip?
how do you remove the dust cover from the M4E1? I need to take mine off.
I have a quick question for you. So I just finished my first complete upper and lower AR15 build and I used an Aero Precision M4E1 Upper Reciever with a quantum rail. I purchased one of their 18" CMV SPR Profile barrels (I believe ballistic advantage is the OEM), as well as a SS gas tube with a adjustable gas block. After I assembled everything I was experiencing an issue where the gun was constantly short stroking. I adjusted the gas block all the way from fully closed to fully open. Unfortunately, the best it ever got was barely ejecting the casing and not picking up the next round. I tried 55 grain, 62 grain, and 77 grains with all of them yielding the same result. I purchased a new gas tube and a standard gas block and the rifle is still short stroking. I attached the upper onto a carbine length buffer lower and a rifle length buffer lower. Still experiencing the same problem. I have contacted Aero Precision and they have sent me a UPS Delivery label so I can return the barrel for inspection. Could the problem be the gas port wasn't drilled quite right? I just have a fair amount of money wrapped up in the gun and it is irritating that this isn't working. I am just worried that they will send the barrel back to me and say it has no problems, yet the short stroking still continue. Bit longer than a quick question, but thanks anyways.
I got option huh? Do I have the option to use any brand/manufacturer or style I want? That upper is just to get you to buy there brand uppers. I'll pass for a more standard upper that gives me way more real option then that upper gives.
Does anyone know if the Midwest industries ss hand guard will fit this? Thanks
Doing my first ar build and this video was so useful, thank you and you sir have a new subscriber
Absolutely love my AP M4E1. Bought mine in the OD Green builders set. Super easy, love it.
What other handgaurds fit this upper?
Do we know if this COP barrel nut will fit over a 1.05" bull barrel?
Do you recommend adding gas block dimples to the barrel?
whats the length of the barrel and hand guard ??
can i use faxon's streamline handguard on an enhanced upper or will the upper receiver only accept aero's enhanced handguard?
Just ordered one. Can't wait til it gets here. Question for you… Is the dust cover assembly all Mil Spec? Can it be swapped out easily?
hi Bob I have a question for you I just picked up m4e1 complete Upper from Aero precision I know they don't dimple their barrels or pin their gas blocks have you guys had any issues with they're low profile gas blocks with their barrels more so their gas blocks loosening up? was just curious if you could get back to answer that question and would you suggest dimpling the barrel
Wicked!!!
Wow. Barrel swaps from .223 to .300 must be fast as hell too. Got one in the mail. I'm stoked.
Love the a cappella at the end!
Do I have to use an aero precision hand guard with the m4e1 ?
My included wrench does not fit the nut.
That is an awesome system. I'll buy one soon.
love the built in barrel nut, I'm going to look into one
anyone figure out how to remove the dust cover on this upper receiver?
Can you use any hand guard with this receiver ?
Grease or oil on the threads? I have always used grease on the barrel extension and nut. Is it needed?
So, no need to check head-space?
Cool Is that a mid length gas tube a 16 in barrel and the 15 in Enhanced MLok Rail. Looking to get one for a 16 in barrel and I'm debating between the 12 and 15 in Rail
I think I need to get their upper for my next build. good video bro. thanks
I like there upper a lot but I ordered a lower from them and mags wouldn't drop freely. Also there barrels aren't really good the already exchange 2 300 blackout barrel I bought from them. And the bolt carrier group I got the gas key is barely stacked and they don't make bcg there . I asked the tech they stop making there own bcg awhile ago. Overall there ok company but can't compare them to colt or bcm, spikes . Etc
Can you put a Troy Alpha on the upper?
I'm impressed. Kinda makes the old design look obsolete. Future AR builds will be with Aero.
Can the M4E1 upper receiver work with any of the existing piston conversion kits?
man, I can't wait to get my M5E1 together.
Love this upper receiver! So easy to put together, no screwing around with timing when you torque down the barrel nut. That alone makes it worth using. Really glad I stumbled upon this upper when I built my first rifle.
nice may have to try one for my next build
can you compare the quantum against the alg EMR?
Nice DIY
Looks like i have a M4E1 upper with the Quantum handguard in my future. 😊
My OCD went on overdrive with the mix colors!
I have 2 of these uppers with a 9" and 15" rails for my Aero pistol and rifle builds; love them!
