Superior Arms Lower Receivers

[ARdysfunction]

I do remember that... I thought you were saying there was a lower that would not work.

The FCG was extremely close as far as tolerances went and and every thing had to be perfectly aligned to fit in.

I have a superior pistol lower and other than it wont accept pmags its been ok. I probably wouldnt buy another one though.
