So here I am with my final 4.5” barrel choice to put my SBR back together, because I got the wrong threads on my first one and I don’t feel comfortable with the thread adapter... comes in, go to install, and instead of the usual barrel pin, I see a roll pin bigger than the receiver spot. What the heck am I looking at? Maybe one of those things that’s common I just haven’t run across.
edit, tapped right in with tiny pressure from rubber mallet, but my question remains!
