Description

Includes:
M4E1 Lower Receiver in Anodized Black
M4E1 Threaded Assembled Upper Receiver in Anodized Black

M4E1 Lower Receiver Features:
Threaded Bolt Catch Roll Pin - Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (pin included).
Integrated Trigger Guard - Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger more rigid platform to build upon.
Upper Tension Screw - Allows users to fine tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.
Threaded Takedown Pin Detent Recess - Allows user to easily install the Takedown Pin detent and spring with the use of a 4-40 set screw (no more launching detents across the room).
Increased Magwell Flare - Increased the flare of the magwell to aid in quick and efficient magazine changes.

M4E1 Threaded Upper Receiver Features:
New enhanced forging that gives the upper receiver a "billet look"
New picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
M4 Feedramps
.250 takedown pin holes
Lazer engraved T-marks

These are nice and a good deal for the M4E1. Mine shipped fast. E-Arms is good to deal with.

Just a few weeks ago I bought a completed M4e1 upper for $69 shipped. Can you make that price?

It's just Minimum Advertised Pricing that went into effect in April. They just can't be listed cheaper. We have a code for 10 off that's been running on them as well - it's AERO10OFF. Everything over $25 is shipped free.

This is shipped free and whoever listed it missed the coupon code. We'll beat any M4E1 shipped price on the internet, just call us. As I posted in another reply, we can't post it for cheaper.

Yep. At $185 it's not a deal.

I liked them better when they were $150 three months ago! Fleecing due to fake news. What gives??

Take note of the suppliers that up their prices when that shit happens and don't order from them when prices are low

We're required to if we want to stay a dealer with Aero Precision. We don't have a choice since it's the majority of our business.

Oh really then just rename the upper like brownells selling same upper you are for $32 cheaper: https://www.brownells.com/rifle-parts/receiver-parts/receivers/lower-receivers/ar-15-m4-stripped-upper-receiver-black-prod116835.aspx...

No, sir. They aren't. Brownell's sells the Aero branded upper for $20 more than we do (before our coupon code) and charges you shipping on top of that: https://www.brownells.com/rifle-parts/receiver-parts/receivers/upper-receivers/ar-15-gen-2-stripped-upper-receiver-5-56mm-prod113665.aspx?avs%7cManufacturer_1=AERO%2bPRECISION...

We are literally selling the same upper for $30 less and we're selling it for only $5 more, shipped, than the Brownell's branded upper receiver you linked.

Again - it's priced based on a policy we are bound to. We don't yet produce our own branded uppers to take advantage of the same pricing structure that you can get on a Brownell's branded product.

Also - here's the link to our Aero upper for reference. It's 63.99 before code. We were selling them for significantly less before the MAP update and we still do via coupon code:

Will a standard upper receiver vice block work with these or do you need to buy a reaction rod?

I was able to use a hinged clam-shell type vice block without issues, or gaps, etc. Attached an 8" CMMG .300 Blackout barrel with ease, and attached a handguard WITH anti-rotation tabs (ACME Machine). Hope this helps. I purchased my set from E-ARMS last month. Almost forgot to mention... the stainless set screws for the forward assist (obviously), and the bolt catch are included, but the rear take down was not... I had some on hand from a local hobby store (#4-40x1/8").

These are very nice receivers, I've built dozens of Rs with both Top Billet and low Forged and for the money these are sweet and well designed. Price can be found cheaper if you can find them in stock but definitely worth a little extra money than any milspec forged. But with confidence!

I just paid 240 for the same set and a 15 inch M Lok from Arrow not a deal

Can you post the link? I can't find it. The lowest price I've seen online is $180 for the set and around $400 for a combo with a forend.

It’s because it doesn’t exist. This guy (tinyursa) thinks Brownells receivers are the same as Aeros which is not true at all. He’s a D.A.

Brownells had the bronze and multicam on clearance for $280 a while back. He might've got that down with codes and GCs
