Got one free. finish is poor but action is tight AND she's got a "0" bolthead that fits VERY tight. Barely lines up with the guide rib, nowhere near over roatating. I'm torn with what to do with it. Of course the 303 is the obvious, and probably best choice, but I'd like something else. I'm not particular as to repeater or single shot capability. Anyone out there ever go whole hog on a No4 MK2?
