JD, I dont get the part about not a whole lot of mounts for a 56mm. I have a picatinny rail mount and I have two different sets of rings. One set is 1/2" high and the other set is 1" high. One of these sets of rings should be able to mount the 56mm. It is only 3mm bigger in each direction, so if my 50mm had 6mm space from the barrel, then a 56mm would have 3mm space right?
