-Dissasemble and lube everything about every 15-20k rounds.-Clean your inner barrel often to prevent build up and jamming bb's.-Check to make sure nothing is stuck in your magwell every now and then(I got a bb stuck in there once and it kept my mags from sitting correctly all day)-When opening the gearbox, don't "screw up" your shims. THis can be a pain in the ass to get right again once they are misalligned or missing.-DONT DRY FIRE YOUR AEG! -only exception to above- Fire in semi auto about 3-5 times to make sure the spring is decompressed after AEG use.
