I had RDTS do mine. Ralph made it into a SD. It really looks nice and functions well. I took emery cloth and smoothed the casting down by hand. Then I had Ralph remove the two cast marks . The only drawback of mine is that I can't put the sliding stock on it. But I prefer the full stock so its not a big deal. I'll try to get some pics and post them. Remember though Ralphs time is not mans time.
