So I went ahead and started in on this tonight since I had picked up one of the threaded aftermarket barrel shrouds so I could shoot suppressed while waiting for my SBR approved. The blind pin......not to bad. Noticed all the info out there talked about either drilling it out or just cutting off the shroud and barrel end, not an option for me right now. So........how about using a dremel. I don't own a drill press or barrel vise but I could rebuild Rome with a dremel tool. Put the little round sand paper grinder on and slowly grind down the opposite side of the shroud from the pin. In a couple minutes of grinding you'll see the hidden part of the pin. Tap it out with a small punch and walla....an undamaged barrel and no gun smithing fees. This all took me just a few minutes. Anyway, just wanted to add this to how you can easily remove the shroud without going to the gunsmith or buying special tools.
