Oh, by the way what do you consider a cheap K31? I ask as I am in a club and deals come my way all the time in K31, JG11 and more commonly, K11 rifles.
If you have a C&R they can be sent directly too you.
Haha well I guess for the K31 would be under 400$, the reason why I asked for the said above is that I have only 180 bucks to spend right now plus some help if I need a loan, and plus I just love the older weapons.
