So I have decided I guess to build my lower, as I am pretty stuck on the Larue MBT trigger, so there is no real advantage (not already installed from factory) of getting a PAS lower over a different lower.

I looked up prices, and Aero Gen 2 stripped lower is on sale at $54, plus I can get $10 off and free shipping, so that brings it to $44. The PAS stripped lower is $40. So only a $4 difference. Is there ANYONE who would take a PAS lower over a Aero for $4 difference?

Also is there any issue with mating a Aero lower with a PSA complete upper? The "slack crew" in the Aero will take any slack out of the setup correct?

For the price MBT cannot be beat. Great trigger and still $87 after Mark said it was going back to full price about a year ago yet it has not gone up in price.

I like my aero lowers....I also have psa lowers.  Get what you like if you have issues with either company they will take care of you.

This. Very pleased with the set I just built on.

Bought a PSA lower a while back.  Anodize color was way off, didn't come close to any upper I had.  Had to paint it.  Have 2 Aero lowers and color is perfect.  I say get the Aero if for nothing else, $4 is nothing.

Where can I find the Aero lower for $54? I'm seeing them for $70+.....?

Primary Arms has Aero lowers for $55. Just picked 2 up the other day.

Aero is my go to lower if there’s nothing specific I’m looking for in a lower.

I will always take Aero over PSA.
