Every time I go to the range, everything I shoot, I clean. Sometimes in the interests of time I don't until the next weekend when I'm around to...but, they always get cleaned.
Obvious exceptions are when I shoot corrosive ammo; those (usually M1 Garands, or an SVT40) get an immeadiate full cleaning.
But yes...I clean everything.
And I don't mean just a simple wipe-down...when I take out one of my AR's, for instance, my usual cleaning regimine includes popping out the extractor and swabbing under it. About the only thing I don't regularly wipe down is the buffer and spring
I won't get into Garands and M1 Carbines...it'd take just as long to explain how I clean them than it would be to actually clean one. (Average an hour...I like to make sure.)
Ak's...same. I break out the shotgun swab and clean out the upper gas tube...squirt enough brake cleaner inside the gas port to clean out 3 or 4 pennies...etc.
I don't like putting away dirty rifles. I'd rather they smell like the final rubdown of CLP, not some surplus smokeless powder.
I want to know that should something weird happen, I'm going to pick up a rifle, any rifle at random, that has been cleaned, inspected for broken or seriously worn parts, and has been maintained. I do that after every session, and a quick once-over before I go out.
But, that's just me.
