Ok gents I need your help. My M40 had some cancer (rust) inside the receiver where the bolt contacts the receiver. I removed the rust but now there is some bare metal inside the receiver. what do you guys use for lube/protection? I was a CLP guy for EVERYTHING until I got educated. I was using frog lube for the bolt, obviously that didnt work. So what are you guys using? Is clp good enough for long time storage? Do you store your rifles with the bolts in or out?
