Do you live about 12 min. from a shooting club or range etc?
You could spend hours per week cleaning, with four 7.62x39 rifles and a pair of .22, three 9mm handguns.
I tend to do internal cleaning on each about once per month, otherwise rubbing somewhat moist patches on the outsides.
Coal Dragger: A young Marine who worked three years ago as hotel security (during our layovers) in downtown Tallahassee served as Infantry in Iraq. He told me that on the first patrol after cleaning, they would see at least one standard rifle jam.
Was it too much CLP, which might have been exposed to the thin dust, or probably just very worn out components?
I doubt many of us shoot in an Iraqi-like environment.
