Have you done any mods to your UR ? I am looking into doing an sbr, just got my paperwork in the mail. I want to add an ak 100 series when I get the stamp back. Do you have the 10 inch barrel or 8.5?
Any of you guys/gals experiment with these? Do they pattern well? Any pros and cons are greatly appreciated.

It is for an SLR106 pistol that I plan on sbring as soon as I finish the legal process. Does that already have the trunnion? If so I guess I am looking for everything else. I guess I will check Russian surplus.
