Hi , I have that scope on a SRH , truth be told it stays on 2 power. So I won't be much help in that regard , but I do like it , after a few cylinders of full power loads the ring for the magnification begins to creep up towards 3x , not really a problem tho.
Mine is stainless , and to be honest I think you are very close to what I paid a good many yrs ago , perhaps I paid $130.00 or so , can't recall where I bought it , it was online I feel sure about that.
