Questions & Answers
What is the small set screw used for?

If you're referring to the 4-40 set screw its because aero threads the rear takedown pin detent channel on their lowers. It's very convenient as you don't have to rely on the endplate to hold the detent and spring in.

Helpful Positive Review Standard LPK - but better! by ck, Verified Owner, March 4, 2022
Always great parts from Aero. This LPK is no different. Somehow they make milspec triggers and hammers that clearly are several grades better than an actual milspec setup. Thanks again Optics for another solid deal on great Aero products.

Helpful Positive Review Perfect fit lower kit by AR Fun, Verified Owner, March 8, 2022
I used this kit on my new aero ar 15. Fits and operates perfect. Everything fit perfect and bolt catch works great and locks up nice. I would say better than most kits on fit and operation. Nice mil spec trigger.

Overall great milspec parts kit. The safety lever has a bit of a weird profile that is off putting.
