Pump, yep PUMP action AK these dont come up very often at all. Very smooth action and shoots real well. Very strange little gun that is an attention getter. This one has no rear sight as it was factory welded and made into a ramp. Why? Hell I dont know. It does have the optic rail on the side so Im guessing its like the "optics ready carbine" AR's.Contact me here on IM or at glenn@acadianagunworks.com
