Most Helpful Positive Review Aero Precision makes great products
I have used several Aero Precision parts and I can always trust they will be of high quality. The lower parts kit is no exception. Optics Planet provided reliable service at a fair price. Buy with confidence.
Most Helpful Negative Review Ar-10 lower parts kit.
The lower parts kit was great until I got to the bolt catch roll pin. This kit doesn’t include a threaded roll pin. Just a standard roll pin for use with aero precision’s M5 lowers. If I would have known that I would have gone with a different lower parts kit

Wrong part in kit

by Dmar, Verified Owner from VA, United States Written on January 8, 2025
The bolt release THREADED PIN was not in kit. Had a roll pin and I suppose one of the small cap screws was to retain it. Not cool.
Pros:
  • Parts got well enough
Cons:
  • None

Everything worked with my Aero M5 308 build

by Sherm, Verified Owner from MI, United States Written on March 29, 2024
Al the parts and pieces were there. Everything fit as it should. However, the spring that holds the detent on the take down pin is quite long. It needs to be cut down to fit but not too short that there won’t be enough tension

Just what was needed

by PJ, Verified Owner from TX, United States Written on January 31, 2024
Had everything needed to build up my M5 lower. Only con is that it has a 90degree safety for a lower that has 60degree markings. Otherwise the kit is worth it.
Pros:
  • Everything minus trigger pins
Cons:
  • 90 degree throw only
Would recommend: Yes
