First Sergeant Sends: Weapons Maintenance
From the MVT FORUM:
I saw more weapons go down this past CTT class than I have seen in a long time. We had popped primers, no lube, not enough lube, wrong lube (grease), carbon build up in the chamber that kept the weapon from going into battery and one case of a carbine buffer and spring in a rifle length AR (with an adjustable carbine stock) that caused it to short stroke. It essentially became a bolt action rifle. The buffer was unmarked and it had a coated buffer spring. All of these issues detracted from training time. You want to be able to get the most out of class, not have to worry about your gun going down.
