Ive had 3 AK style rifles and sold them all. Two Saigas and one Romanian. They were fun to plink w/. Eventually Ill purchase another, probably an Arsenal modded Saiga. Saigas are great rifles. I will say the Romanian was cool to have around.
The Romanians all went up in price recently which sucks. It makes the Saigas even more attractive though.
For me the verdict is still out on the 5.45x39. However, it sure looks good for the pocket book.
The thing is if you're wanting an AR don't let the price of ammo stop you. You can get .223 for around the same price. If you want to send 7.62x39 down range get an AK variant.
