I agree. When I get a firearm, wether new or used, I detail strip and inspect. I clean thoroughly and lube with Ballistol. Weapons like Mini-14s and M1icon Carbines, I run a smidge of RIG gun grease in the bolt track area and op rod (slide) and bolt cam points.. If I just have a range session and shoot say 20 to 200 rounds, I field strip clean the bore and bolt, and reassemble. About once a year, I do a detail strip and inspection again. When I was an active LEO, though, I did complete strip and cleaning every time I fired my duty weapons.
