I have NEVER understood why people will pay $600-$700 for an imitation or even a rebuilt (read: USED) AK from China or the Balkans, when you can get a new-in-the-box RUSSIAN Saiga, from the Izhmash armory where General Mikhail Kalashnikov still works, for around $400 (I got mine for about $350). So it doesn't LOOK all martial and Red-Dawny with the zoomie pistol grip and the crude little short stock; what do you want, a weapon that is BUILT RIGHT and WORKS, or one that LOOKS cool? You can even get aftermarket 30-round mags that work in an unmodified Saiga for around $25 each.
They're all semiautomatic, right? You're not going to get a "real" selective-fire AK for less than $10-15K, right?
So what's the problem? Buy a Saiga and spend the extra money on mags, a red-dot sight, and a thousand rounds of ammo.
