Lube the rails on the bolt carrier, the bolt locking lugs, the bolt body, the cam pin, and the chamber inside the bolt carrier where the bolt rides. Use a heavy lubricant like CLP, Weaponshield, or MGL, and apply generously. If cycling starts to get sluggish after a few hundred rounds, squirt some lube into the vent holes in the side of the bolt carrier and keep on keepin' on. Cleaning the bolt carrier assembly regularly will reduce wear on parts, but an in-spec weapon firing good ammunition should stay running indefinitely just adding more lube when it starts to slow down. If you can afford enough .243 ammo to wear out the bolt assembly, replacement parts are just pocket change anyway.
