Call it "Middle Age Crazy," or in MY case, "Old Age Crazy," but I just like what I've read about this cartridge. I've been talked out of getting an upper in 7.62X39 for my AR many times over the years, due to unreliable magazines, etc. I just like these intermediate rounds and thoroughly enjoy the AK immensely. Always thought it would be fun to shoot the same round in an AR. Anyway, I just received my Advanced Armament upper last night and am anxious to pop it on my Bushmaster and try out some of these dollar-a-shot rounds this weekend. I don't keep up with the AR world that much, but I just don't see how this round is not going to be fairly successful over the next few years, which will assist greatly in making less expensive ammo available. If I'm wrong, I'll just get some reloading dies and roll my own - might do it anyway. First thing I did was load up a magazine with the sixty rounds I do have just to confirm that they fit fine in existing AR magazines. They do, of course. Pretty cool. I know UMC is supposed to be offering less expensive ammo soon. Has anybody seen any of it available yet anywhere? Thanks, Hickok45 Wanna kill these ads? We can help!
