As you guys probably know by now I have gotten to know my way around an AR a little,but know entirely nothing of AK's,Saiga's,and their varrients.How many are there and how would you distinguish the diffrent ones?I want to pick one up soon,and want to know a little background on the diffrent ones out there,price ranges,quality,ect...I am not affraid to say I dont know about something,this area is completely forign to me..
