Whose lower parts kit do you all recomend? Im thinking about one without trigger so i can maybe use a triggertech trigger. Also thinking about using a Magpul grip and trigger guard. Also anyone know where a person could find a 4-40 set screw for the rear takedown detent hole on a aero lower? Also would a person need to shorten the spring when using the set screw?

Thanks
 
I just put together an Aero Lower with a RRA Ergo LPK and it was the smoothest one going together yet in the 5 or 6 I have done. Pretty good stock trigger. Much better than the DD.

I had a grip and trigger and did not need a trigger guard so bought a CMMG LPK from CTCS.
Various options available depends what you want to spend https://ctcsupplies.ca/collections/lower-parts-kit.

4-40 set screw, any fastener supply place should sell them.
Note that I could only find 1/4" long ones locally so ground mine to 1/8" long. I tapped a thin piece of steel and ran the set screw into it and hit the exposed end with an air grinder disc.
Yes, you cut the spring shorter by whatever the length of the set screw you use.
