Does this fit on a PSA ar10 lower?

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on November 29, 2019

No, they will not be compatible as PSA specifically states they ONLY recommend their uppers and lowers together and they state they do not recommend anyone use anything that isn't a PSA upper on their lowers, especially depending on the Generation of PSA lower.
