It sounds like a hell of a lot of fun to me, a SAW type gun firing that devastating of a round. I was also thinking that if you were going to have a Kalashnikov .50cal, why not make it a RPK (has nothing to do with the fact that they are my favorites, lol). The 24" heavy barrel with a muzzle brake and clubfoot stock I think would help out with the beefier recoil, which Meepers said was like a 12 gauge in normal AK config. After talking with Meepers it sounds doable, if a little pricey (but no more than any RPK). So what do you think?
