I too just received a MkII from Gun Parts Corp, and it looks like a decent quality reproduction. I do however believe that I have an issue with mine (unless I am completely missing something here). Once mounted into a reproduction No 4T mount on my No 4 T rifle the reticle is canted counter clockwise by about 5 to 7 degrees, which is very noticeable. I have been reading all of the mounting and adjusting instructions and am to this point under the assumption that there is no adjustment for this since the scope has the small peg screw that locates into the slot on the mount. Im quickly thinking I may have gotten a defective one. Anyone else seen anything similar on these?
