About every 200 round mark, slightly pull back on the charging handle until you see the bolt gas rings move in front of the carrier exhaust ports, then add a few drops of CLP (or a quick shot if you are using a spay can) into one of the holes, then relock the bolt closed.  This will add CLP to the gas section of the B/C, and the CLP will be migrated through out the action during live fire to re-lube the parts.
Using this method, I have taken rigs past the 4000K mark without cleaning.


Now the real question come down to what type of shooting you will be doing before cleaning.

If your target shooting, then you may find that the bore should be cleaned to keep the rifle from spraying, over just adding New CLP to just keep the rifle running. At what point the Bore needs to be cleaned will be determined by the size of the groups, hence the point that the bore has fouled to the point that you are no longer grouping, but just spraying down range.
