Decided just to keep the Sumtoy mount on the M1 and modify some screws for the Scalarworks mount for the Super Nova. I shortened a couple 8-40 screws I had for a Benelli Picatinny mount and mounted the base this morning. It is solid and low and I really like it, hope they make it for other guns down the road. Do I think its worth $100, maybe, but I don't know that I would take a Sumtoy or Burris 336 base off to replace with a Scalarworks but if I were setting up a new gun I would consider it.
Now I just need to purchase a Holosun for the Nova.
