MARS -L and Atrius FRS
So I’ve seen the discussion of how the LMT lowers have a high shelf and require removal of some material in the lower. Also so how much material some removed.
I guess I don’t want to void any warranty LMT may still offer on the lower although I heard it’s extremely difficult to get them to honor those. So trying not to Dremel anything.
Using stock enhanced BCG, stock H2 buffer, stock trigger. Any tip on how to get the FRS to run properly?
