I had a good chat with designer of the copy service rifle this morning before the show opened , the two prototypes are made from stainless, one fitted with a service stock, the other a gary cane stock, the barrel isnt interchangeable like the original or tapered, i asked them if they were going to fit steel sights and peep sight as per the original, but i think there going to stick with the alloy ones, also no aperture sight, which seems a shame, the production rifles are going to be blued, he is going to do a modified version and try to get 12ftbs, should be interesting to see if it works ok.
