go with the 1200mah stick/rectangle one..I have one and it fits into the crane stock...into a CM16..
I have a pair of 1300mah nunchuck too...they stick out of the stock..wont fit at all..but it will fit into my AK74
I would say go for full metal..I'm pretty weak on strength, but I can use a full metal AK for a while..you have a big chance of banging the gun onto different objects, so metal is just much better. Unless you go to big game events, I doubt you will carry your rifle for more than 1 hour..every game is like 20-50mins at normal drop in days..
Its mostly the price your are paying for a plastic body is just a few dollars short from a full metal..doesn't seem worth it.
