Mark series cleaning tip

If you have lite strikes or FTF's once in a while you might when cleaning your MK to check out any build up of crud on the bolt face and around the firing pin and on the chamber face. This buildup can almost go unnoticed while cleaning the bore, but over time a thin buildup of burnt powder will get packed against these parts causing the bolt not seating as close as it should and some rounds won't be struck by the firing pin hard enough. Another place to check is the slot on the side of the chamber that the extractor fits into when the bolt is in battery, it will also collect dirt causing the same problem.

Rimfires are dirty. Clean out every crevice as gunk builds up fast. Don't neglect to clean your magazines either. Another very important spot to keep clean is the hook on the extractor. As soon as dirt and unburned powder collect there you will begin to have FTE malfunctions. A clean .22 is a happy .22!
