Sorry, I don't post much in here but I have a dumb question. I have S&W 5.45 barrel that has the feed ramps installed. I also have an A1 upper receiver that I want to mate it to. Will these two work together or am I going to have issues? Thanks in advance.

That would work fine. It's a rifle extension paired with an M4 cut upper that you don't want.
