Ok thanks. 
I was unclear if the 7.62X39 ammo 
would go through regular. 223 AR
magazines,  but I didn't pose the 
question correctly. I did have a 
really nice AK at one time, but it was
more valuable to another man and 
he had cash that needed to go 
somewhere besides his wallet. 
If I do get this AR, it'll be one of 
those beggars can't be choosers 
kind of deals, but I was interested 
if I could change it up if I was so 
inclined, or if I'd be stuck with 
the 7.62X39 configuration
