After I finish firing the rifle (i usually go thru around 300 or so rounds each trip to the range) I break down the rifle and pull out the bolt and bolt carrier, take all that apart, spray everything with CLP and either wipe down or scrub some with a nylon brush if needed. Then I use Slip 2000 EWL (Extreme Weapon Lubricant) to lube all the parts. (Other parts are cleaned and lubed as well but this is answering your question )

I used to lube with CLP, but it dried too much between range trips and lubrication suffered. So I tried Slip 2000 EWL and its fantastic!! Its great at keeping the rifle "wet" between range trips and keeps everything running smoothly. I heard the Slip 2000 cleaning products work very good as well. I will probably switch when I use up the CLP I have laying around.

Hope that helps
