Perfect if you are building a AR9 not all the extra parts you don’t need
Doesn't include important pieces
by JasonS -
Doesn't include the roll pin for bolt catch or mag release assembly. To be fair they aren't listed.
The quality of the parts seems significantly better than some of the other lower parts kits I've used. Finish on the bolt catch and safety selector are definitely better then most. Only annoying thing was my kit was missing the bolt catch plunger and instead had two safety selector detents.
FCG is not all that is missing here

Who sells a LPK w/o a magazine release? Aero does. The rest of the stuff was great, but be forewarned you have to buy more parts.
No Mag Release
by Rick -
Warning! Note that a magazine release is not included! Why?? Everything fit fine in the M4E1 lower receiver. I used an alternate Ambidextrous Safety not the one supplied in this kit.

Well-made parts, good fit. Installed into a 17Design billet lower without any issues.
***Kit does not include magazine release assembly, order separately***
Could be better if wasn't missing parts
by Gregg -
Aero's quality control in the packaging dept needs an overhaul.
missing a few significant small pieces
Pro - it came with two bolt catches
Con - missing bolt catch buffer
Con - missing safety selector detent
Con - while it's not listed here or even on the box, it would be nice to have the bolt catch roll pin. which is listed on the included parts on Aero's site for this SKU: APRH101330
Just what I needed

Just what I needed to finish of my lower.
Perfect fit and operation…but be aware of this:
by Mr Ed -
EPC9 got fitted perfectly with no leftover parts!
FYI: I used a Colt M4 trigger FCU and found it has has a shorter length hammer than a regular milspec hammer and would not reset properly with the Aero 9mm bolt. So I replaced it with a regular S&W Milspec FCU and it worked perfectly. I always thought they were all the same dimensions… But it tain’t so!
Read and heed the Aero bolt box warning label!
Typical Aero trash
by Steven Morgan -
As usual from Aero, over promised and under delivered. Lower parts kits missing mag release, mag release button and spring. These are NOT complete less FCG. I’m done with anything Aero
