The metallurgy in the trigger group is suspect and when introduced to Kodiak-style rain it oxidizes so fast the linkage wire freezes the trigger to a locked-up and useless mode. Generally it takes about three days of "Tuesday" to cause it. Few make it past a week. If they do they will likely never be a problem.
So, y'all don't have OIL up there?
(Or enough sense to keep your guns dry?)
