I'm trying to swap out the barrels on my carbine.  It's a Bushy ORC, so it has no front sight post or rail to attach a flip sight.  I have an RRA carbine barrel assembly (complete handguards, delta ring, etc)  that I want to use in it's place because it has a standard FSB to use with my YHM flip rear.

Problem is, I have an armorer's block and AR wrench, but no damn vice to clamp it in.  Anyone in the Sterling area have one I could use for a few minutes?

I just use a big wood working clamp and clamp the action block to my workbench.

And I'd loan you my clamp but I got to head out early tomorrow morning.
