Hmmm... Now that's interesting!
So, with a Romy RPK trunion, I'm wondering how that would work attaching the trunion when the receiver is wider on the 47ES than the regular 47??? Would I need 'shims' or something to fill the gap?
Hmmm... Most interesting. What thickness(es) of Flat Bar are you using?
Hmmm... I'm guessing if done with a screw build format like this, you could probably later go through & rivet the whole thing together, right?
I'm most anxiously awaiting the build thread on this! The sooner the better!
