I have an DPMS M4 that I want to swap the A1 Reciever for an A4 Flat-Top. I understand how to remove the barrel and all that, but the gas tube roll pin on the FSB has me a little confused.
1. Is this supposed to be a solid roll pin like the rest on the FSB?
--Mine is hollow and I'm a little hesitant to hammer a punch in there without knowing the exact diameter punch to use if the thing is indeed hollow. I can't tell for sure because it just looks like a hole that runs all the way through the gas tube.
