[@justanotherinternetexpert7743]

ABOUT FREAKING TIME! .....Aero Persicion you guys kick ass, but this was long over due!!! ....better late then never tho, so BRAVO JUST THE SAME!!! ....Too bad I can not buy one tho, because I live right down the street from your factory In Tacoma, Wa. And Bob Ferguson pushed thru his assault weapon ban last year!

[@D3IVIO7V]

Pardon me while I take an Inslee and wipe my Ferguson.

[@justanotherinternetexpert7743]

@D3IVIO7V hahaha! Bob Ferguson is an absolute P.O.S. scumbag! ....I really hope he does not get the governor job he is seeking right now, but the way the Sheeple of western WA vote he will probably win. I am gonna move to a deep red sta

[@Idlesheep]

What I love the most is the absence of your logo❤

[@MathewReed037]

I just ordered one, having it shipped to my local dealer. I also placed a subsequent order for other parts to complete it. I want, or rather need, that awesome Mod 4 handguard!!

[@Killa91115]

How much?

[@elucky3fortune130]

Been waiting for this for a while! Premium build for sure!😎

[@Samos900]

Aero is the change I’ve been wanting to see in the world

[@mrshort2379]

I have to say, now that's an Ambi Lower Receiver. It is about time Aero Prec. finally made/released an Ambi Lower. I just hope it is reasonably priced. unlike most other Manufacturers, wanting a unGodly price for theirs.

[@rb7922]

Suprise! It's not, $320

[@msquared9605]

Griffin armament is $200-$220. Just got mine and built it out last week. I love everything aero but griffin’s Ambi bolt catch/release is much more ergonomic And fyi, griffin mk2 lower is the exact same as ADM’s, but half the price. They actually collaborated together on it but apparently business went south

[@rb7922]

@@msquared9605 that's the next one on my list, I have a Lancer that doesn't have an ambi bolt catch but it has a neat trick with the magwell

[@msquared9605]

@@rb7922 tbh now that I have it, I see no advantage in it to my bad lever or phase 5 Ambi bolt.. I just wanted it for the cool factor of having a full Ambi gun lol

[@08ChrisMC]

​@@msquared9605 The advantage is you just don't have to have the BAD or phase 5. I'm running a BAD on my gun currently and from what I can see, it would get in the way of most ambi mag release options. Griffin killed it with the MK2 and its price point. Right now at primary arms an M4E1 stripped lower ($40 off), phase 5, and Troy ambi mag release is $208.98+ tax. Why would you ever do that when you can just buy a MK2 for the same money?

[@RuBearUSA]

Can you install a left handed upper on this lower?

[@dwilliams321]

You can install a left-handed upper on any mil-spec lower. The only thing you need to make sure you have is a left-hand BCG in that upper. Ambi controls make it nice to use with a left-handed upper, though!

[@tanman47756]

I just ordered a Griffin Mk2 Ambi lower, this would have for sure been a consideration. We'll maybe have a future setup down the road, looks clean.

[@msquared9605]

I just built my mk2 last week. From the looks of it, griffin’s Ambi bolt manipulation seems much more ergonomic. Especially for my smaller hands not having to reach all the way to the top of the receiver. But I also have a bad lever and phase 5 on 2 other guns. I see no difference in any of them

[@tanman47756]

@msquared9605 How long did your Mk2 take to ship out? They said it's a high demand right now so they are behind on orders so just curious what your turn around was. Good to know, I've have bad levers and the phase 5 on rifles and seems like the Griffin is pretty ergonomic from what I was able to find.

[@msquared9605]

@@tanman47756 Aw man I saw the same thing on griffin’s site and was about to order from them and wait but after doing more research I found some on rainier arms. It was free 2 day shipping lol But no doubt it’s ergonomic, best Ambi bolt placement of any lower! I just mean I don’t see a huge advantage in it because as a righty, Ambi mag release means next to nothing. I just wanted it for the cool factor of a full Ambi gun

[@thatboygerv]

​@@tanman47756 It is a high demand, I ordered mines April 3 and my FFL got it may 15th but looks great. Haven't put it on because literally just finished my upper build yesterday day

[@DrSpas]

Not bad I of course will have to try one I dont think it will beat my preference for the hk a5 ambi bolt catch, though Still a must have How do I get aero to make me an m4e1 lower factory milled and finished for the HK?

[@brorx4475]

Looking forward to a M5 pro lower

[@stephenedwards5063]

I preorder this product and I’ve reached out multiple times, but I’ve yet to receive a response. Can someone tell me when these will ship? Not sure what happened to Aeros customer service but I shouldn’t have to message 6 times in regards to a product that was supposed to ship September 9

[@m4e1supremacy]

Hell yeah

[@yusukeu9968]

This awesome product, I hope it’s reasonable price. Sad part is that, can’t buy in Washington state.

[@justanotherinternetexpert7743]

I am right there with you I live right down the street from Aero's factory in Tacoma, WA.....Freaking Bob Ferguson is the worst!!!

[@codyboland8109]

Unfortunately it’s $320

Aero doesn’t need Washington State, there’s almost 40 other states they can still use for now

Corrupt government isn’t sad

[@InvidiousIgnoramus]

Hope this one doesn't have too much of a flare like my PWS lower. it's just big enough to interfere with gen 3 pmags.

[@jesus2299]

Can you guys make one for Ballistic Advantage I want the clover.

[@shirolee]

Hell yes!!!

[@Many-t5n]

They should have included the cut outs to the trigger guard from the m4e1

[@outboardprsnlstndup]

Now do M5e1 lower!

[@davidwithers7181]

Am I blind, not seeing the pro series on the site

[@gordonliddy9418]

I love aero but these lowers are pretty spendy. I'd honestly opt to get an lwrci lower for the price.

[@celze20]

Coming in at $300 as a stripped lower...since it's forged, they passed on the savings to us. I'd rather have a silencerco lower with qd points for cheaper.

[@manofthepeople2165]

I’m gonna wait for the price to go down. $299 is a little high for a forged stripped lower, I feel like $200-250 is a better price point.

[@JADC1111]

$1900 for a full pro rifle? Craziness

[@toddparsons2980]

Want and want 👍👍

[@D3IVIO7V]

Can't wait to be a free Washingtonian again.

[@CampDavid54]

Good one

[@jamesdoehler9870]

$300 ? For ambi features .. why so high .. I just can't see paying over 100 -150 for any lower .. how do you justify $300 for this lower

[@jeffcooper5026]

Done with Aero.. customer for nearly 10 years. I just picked up a OD Green M4E1 lower from my FFL and the finish looks like it has grinding marks after it was anodized. Contacted Aero and they blew me off because I didn't buy it from a "Retail Partner" Brownells/Optics Planet.. so if you buy from Mom and Pop you are screwed.

[@grabarzowaty]

Do you ship to WA? jk

[@CampDavid54]

Good one, then governor Ferguson black boots could visit them

[@Pyreleaf]

Now do M5s

[@bigfootdrums]

I don't think I'll ever buy an ambidextrous lower receiver, just a personal thing, but I always avoid anything proprietary, and until the whole industry settles on a design for an ambidextrous lower receiver, I'm out.
