Since Aero is no longer in the game what lower parts kit will work well with them? I have at least three maybe four Aero M5 lowers to put together.

I would think any "mil-spec" LPK should work.

That said, the Aero web site shows the MOE LPK Minus FCG in stock.  This and a LaRue MBT trigger and you would be golden.


Aero LPK

I stand corrected.  I looked up the M4 parts kits.
Nobody is coming. It's up to you.

Aero has been tits up for a while... that's why Aero LPK's are going for crazy money on places like GunBroker.

The issue you will have is the take down pin and pivot pin. The Bolt Catch can be sourced, I believe any DPMS LR or similar will work, but the pins are the problem. I want to say Strike Industries has pins that will work but I'm not 100% sure.

Aero has new owners and say they are coming back according to the email I got a few days ago and their website.

I'm curious as to why you say the pivot and take down pins are different.  And bolt catch for that matter.  All mil-spec as far as I know.

ETA:  Never mind.  I was looking up the M4 parts.

I was at a show over the weekend and one vender had a parts kit from XTS. Has anyone had any experience with these? I saw in a previous post that the CMMG MK3 kit was good to go.

Aero is coming back. Just give it some time.

Not sure if it is the lead time with financial backing will gets things fired up again.

I would give it a couple of months to see if they are back with a large inventory before Black Friday.

The biggest issue is the take down and pivot pins.

Rest of the stuff can be overcome more easily.
I have 4 spare receiver sets but only two lpk’s.

Even the STAG line has different pins. One is dpms (Aero) and
Stag is Armalite cut.
