speaking of big knives... been wondering of I should turn my waki into a payment on a AR15 in 7.62x39. want to get another hicap rifle before the disappear off the shelves again.
If I were you, I'd take no chances and use the right while it's still mine to use. Especially when you have options in financing it all. Deciding factor for me would be ammo like I think Hobbes already mentioned. Availability (distribution), price and quality. All within the realm of you being able to actually make effective use of it off course.
My E0.02, YMMV
