It is too bad about the butt pad. It is 8mm. The magazine is pretty strange. It seams to have an internal stripper clip built into it took me a while to get it figured out. Not friendly for field reloads, but it looks like it can hold allot. The craftsmanship is amazing. I still cant get over the trigger, its like a 1 pound pull maybe..it nicked it and the firing pin slammed forward.
