Is that why my Saiga hits low and to the left at only 25 yds. How do I fix this? Does the AK require a special tool to adjust the sights?
Places like CTD, Tapco, and I think CDNN sell the tool to adjust the sights. You have to screw the post up or down for elevation and use the mini vise to push it back and forth for windage.
"Cant" is when something like the gas block or front sight base is not installed straight. Sometimes this can be dealt with in the sight adjustments if it isn't too bad but other times the FSB or gas block has to be realigned.
Yours most likely just needs the sights adjusted.
My experiences with AK's are as follows:
VEPR K 223 - Very accurate, well made, and utterly reliable. It would shoot 1.5 inch groups at 100 yards (prone supported) with UMC 55 grain ammo. It was poorly balanced for my tastes so I sold it.
SAR-1 - handled like an AK should but I couldn't hit crap with it (which does not mean that it wouldn't shoot. Just means I couldn't hit crap with it.) I sold it.
Arsenal SA-M7 Carbine - utterly reliable, good balance but a little more weight than the SAR because of the milled reciever. A good compromise between the VEPR and the SAR-1. Accurate enough to consistently break clay pigeons at 100 yards and put large peices of them in alot of danger.
I also have another SAR-1 on layaway. I don't know why because I doubt that I will be able to hit crap with it. Still though, at $280 OTD with everything straight and two 30 round mags, I couldn't walk away. It may get customized or turned into and AK-100 series knock off, but it will be mine.
