I do actually have experience with them and Ill tell you this: Not worth what they what for them.

Now the question is what do you want it for, just to own an AK or for a specific purpose?
A lot of times people overlook the simple WASR, but its just as much if not more of an AKM than the Arsenal.

Your best bet, buy the Saiga in the caliber you desire and convert it yourself. Ive done two of them. For the money you save you could buy a few thousand rounds to go with your new rifle, and have gained a lot of experience and know-how with the AK platform.

But again I ask what will the rifle be used for?
If its a SHTF gun, then 7.62x39. Its the round that all others are judged by on the modern battlefield.
If its just going to be a fun range toy then the 74 for sure. Ammo is STUPID cheap. I mean I stocked up on it a year ago and the price hasnt gone up at all. Only thing cheaper is 7.62x54R.
x39 is actually becoming hard to find on the cheap. I just bought my last 5000 rounds of the Yugo M67 ammo. It seems that the supplier says they will not be importing any more of it.
