I went to that link and yes, they look like it can be fun. I noticed it appeared to be a new set-up, all around, to get that to work. I have been thinking of getting a 7.62x39 insert or 5 for one of my 303s just so I can shoot that Ak round. That set up looks like fun. Should be interesting to see how they compare to that other modification being made for both 98/48s and SMLEs to handle the 45 acp round. Wonder if anyone has gone that route yet?? Mikey.
