Aero Precision M4E1 complete upper

[pag23]

Hello,

Local gun shop has one for $479 less BCG and charging handle. It is an MLOK rail 16 inch barrel.

Usually I get BCM but they are out of stock...

This is for a back up AR, something more for the range.amy pros or cons?

Thanks for the comments

I'm a noob, so take my opinion for what it's worth, but I'm pretty happy with my M4E1 complete lower and stripped upper that I bought. Quality seems very good on the receivers.

One issue I did run into is that the M4E1 upper doesn't fit in a standard vise block, so if you plan on doing any work to it you might need to get a reaction rod or modify a vise block (avoid this option if possible) to fit it - not sure if anyone makes one that is compatible.

Our local shop sells a TON of Aero Precision and the feedback on their FB page is very positive.

You'll be fine. In 2020, I assembled 8 carbines on M4E1 complete receiver sets. No issues with the upper or lower in the usual checks that are issues for some manufacturers (upper index pin slot/feedramp alignment, buffer retaining pin, tight magwell, etc).

Some of the Aero Atlas rails are a little thin for my taste, especially if you're bolting things like IR lasers out front that need to stay zero'd. But probably a non-issue for you.

If it's in stock and you have the money, no reason not to.

I used an Aero 16” mid length upper on my last 5.56 build, it’s performed flawlessly. It seems to be smoother than my BCM with a carbine length gas system and it’s every bit as accurate. I would use Aero again without hesitation.

If you see it and you want it you better get it. You’ll kick yourself if you don’t and it isn’t available when you go to purchase.
Aero is gtg.
Quality complete uppers with bcg and CH are in the $700-$800 range. So I don’t see that full upper sans guts being overpriced.

Do you have a bcg and ch on hand for it?

Not a bad deal in today's climate. I like the M4E1 receiver sets and have used them for builds. I usually use other components to finish off the guns as i dont love their rails or lower parts (kits/buffer tube) but they are decent quality overall

They own and use Ballistic Advantage barrels which are overall pretty accurate and decent quality. Def a step up from the psa, anderson, etc..

Not to derail the OP's thread too far, but can you expand a bit on your comment on their lower parts kit?

No BCG or Ch, but they have them in stock at the shop...$130 for phosphate BCG

Aero’s QC has always been hit or miss and it has definitely gone downhill since the rona panic.

Do you have examples of the latter claim?

Yeah I had personally had to send back two out of spec lowers and also had another two with shitty machining including uneven cuts in the fire control group leaving one wall on the side thicker then the other.

I have also seen numerous issues in the SOTAR group on Facebook and others ranging from mim parts, out of spec lowers, improper gas key staking, unstaked castle nuts, bolts breaking, just general improper assembly etc.

Aero is not something I consider duty grade and would definitely push people in the direction of BCM/SOLGW.
