I am looking for an AK. I really like the Bulgy Century AK-74. It's a bit cheaper than a WASR and probably better quality. I own an SKS, so I already have about 200 7.62x39 rounds. I've never shot a 5.45x39 rifle, all I know is ammo is really cheap! I am however worried about future ammo availability. Will 5.45x39 be available in 10 years, 20 years? I'm sure surplus will be long gone by that point. Should I just pay a little extra and get a WASR-10 or are these CAI AK-74s decent?
