Apply BoltLube liberally!  Wetter is better.

 

AR style rifle bolt carrier groups, and others, burn off lubes quickly.  Many products turn to sticky goo after just a few magazines.  BoltLube™ resulted from frustration with commercial products, and it:

  •  Stays where you put it, like rails and rings of an AR bolt
  •  Not get gummy or sticky like that "three letter" stuff
  •  Suspends carbon and Direct Gas Impingement residue
  •  Flows when cold, stays viscous when hot
  •  LUBEs better - uses METAL-PENETRATING-LUBRICANT
