I have a question about uppers. I was going to replace a barrel but now I have decided to build a new complete upper and I have seen some listed as A3 and some listed as flattop with M4 feed ramps, what is the difference if i get just a stripped upper and put a forward assist and dust shield on and go with it?

A3 does not have ramps the M4 does. They will both work. I have both running perfectly. Greg |
