So the Patriot Valley Barrel nut arrived by the time I got home from church today, it spins on the threads beautifully, but the collar meant to cover the exposed barrel threads won't fit over the non threaded portion of the barrel shank. So, I either salvage the factory nut, which may not be possible, modify the Patriot Valley Barrel nut, or turn down the shank of the barrel. Two of those options are going to require a lathe, and one a special barrel wrench. So, a little delay. I'll get some pictures up later to make it clear...
