Does anyone know what the rate of twist is for AKs in 223? Specifically the Saiga, converted Saiga (presumably the same), SAR-3, MAK-90, and VEPR II? I'm specifcally hoping to know if they'll shoot longer, heavier bullets, like SS109. Anyone have good reports on their accuracy? I know this sounds crazy, but I'm considering one against an AR, and accuracy is #1 priority, but price matters too. And Mini-14 is out. I've actually heard that some AKs, like the VEPR, can be pretty darn accurate. Next question, what competitions would they be allowed in?
