Never heared of damaging an AR by over cleaning them. What does it do to them?There are some exceptions like if you use lead rounds, dirty ammo or corrosive ammo.
Colt claims that you do more damage to an AR by over cleaning the barrel .
Gas Piston AR wipe it off put it away about every 500 rounds unless it is going to be put away a long time a cleaning with CLP done.
Hand guns wipe down after use few hundred rounds break it down clean it. Full strip down maybe once a year.
CLP does a great job of protecting a weapon even when not in use it has never failed me
