The whole benefit of having these guns in 7.62X39 is that a person can finally afford to shoot an M305. Its not about having another gun to shoot the ammo, its about having cheap ammo to shoot the gun.
Ive always wanted an M305 but I simply can't justify even surplus 308. Its way too expensive. Now, I can have an M305 and shoot it cheap. If I wanted a gun that was the BEST at shooting 7.62X39... id go for a VZ58... at around $1000 its a better gun than the Mini 30. So arguing the This gun doesn't make sense because there are better guns to shoot 7.62X39 is missing the point. Even still, arguing the mini 30 is the best choice is silly IMO. Its not.
