Love aero but dude has a ton of personality lol 🤦♂️
When utilizing the set screw for the takedown pin, does the spring need to be shortened or changed in any way?
Building an aero lower for a Daniel Defense upper
Would this work on my f1 firearms king fu 15? Or any basic ar in general?
You guys make an awesome product… the only problem for me on all of my aero precision builds is the fact that there is too much slop between upper and lower receiver.. i know the nylon tipped screw is there to help but it pushes up on the upper and creates unnecessary gap and also does not do anything for the front portion of the receiver… might I suggest oversizing the locking lugs 1 thousandth over to help with that… if you have a better suggestion please help… would like to just buy a lower from you that works and not have to buy oversized take down pins from other manufacturers
Can you use an M4E1 complete upper with the X15 lowers?
Ruger sold me a defective lower, so I'm not buying that brand anymore. Going with Aero Precision now.
The 308 lower has 2 springs that are captured by the handle, but there is only one hole to aid in this process. Adding a second hole to a standard handel would eliminate the issue, I would rather have a hole and not need it on the 15 than need the hole on the 308 and not have it.
This end plate 440 capture plug and spring is a nighmare. How for the love of live are we the builders supposed to get that spring compressed to the point where you can thread the plug in the hole. I am a fan of your lowers both the 15 and 308, however your name is Precision but your part kits are just standard kits. Small efforts can yeild the largest rewards, cut the spring and drill a hole.
I will never buy any other lowers simply due to these having tension screws. Genius
Are the parts between both interchangeable??
Will these take drop in triggers for Milspec lowers?
I love my M4e1 and I just bought another but this time I bought the x15 though background check got delay. Fcking covid.
I just love aero lower my friend and families has Anderson and palmetto and you can tell Aero built like a tank.
People really love these, wish I found some M4e1 lowers in stock. I settled for a Gen 2 of the older one, but it still should be solid when I get it. Hope this race settles down enough to get the newer one at some point.
Just bought 3 X15 lowers at Turners even the employees were mad cause they only had like 5 instock
My M4E1 is a quality lower that looks great too. Thanks.
Does it come with the 440 set screw that goes behind the end plate?
Best bang per buck in the AR world
Can I put the m1e1 upper on the regular aero lower or will it not fit as smooth?
Perhaps Aero Precision can confirm, but appears there is another difference:
the X15/Gen 2 comes in five color choices – Black, FDE (tan), Burnt Bronze, Olive Drab, or Tungsten
the M4E1 appears to only come in two color choices – black or FDE
When are you guys going to be re-stocking the M4E1 lower receivers? Every time I log onto to your site it's sold out before I can put my order through.
This is all great but doesn’t help me if Primary Arms who is local to me can’t keep these in stock. Needing a M4E1 stripped lower to complete a build but having hell getting it. Almost tempted to buy a Anderson since that’s all they have left.
Are all x15 lowers considered gen2 ?
Do y’all suggest using some lock tight on the bolt catch set screw
Cant go wrong with Aero products. I would love to see Aero make a bolt action upper.
Wow! Curtis you're at Aero now?
Seemed like a few months ago you were at Bullseye! …and already a spokes person?! Wow
So, why not include the 4-40 screws? Jeez!
Also I have been patiently waiting … when is the release of the Aero Precision new 9mm lowers and uppers going to be hitting the market? Gun enthusiast would like to know👉
It would be really nice to see you guys designate an M4E1 pistol lower like you have none for the X15/Gen2 pistol lower. Thanks 🇺🇸

Old Kirkles is back at it again.
I love your products, but you need to tighten up your inventory labels. Someone put M4E1 Enhanced Upper Receiver UPC labels on stripped threaded upper receiver boxes. I was told I'm not the only person this happened to. Luckily I found one elsewhere because M4E1 Enhanced Uppers are pretty much sold out everywhere. With these extended shipping times, and the hassle of having to return an incorrect item, those boxes need to be labeled precisely.
where's the AR9?
Love all of my aero! Just completed another pistol last night. Thanks for the video
Good to see thank you for the video. 🙂
So can we please have the M3E1 with no logo?
M4E1 no doubt about it
