What is the best way to lube a magazine tube and friction ring on an old A5 shotgun. Today I got one out and the lifter wasn't working well. I sprayed some Silkroil on it and it took off working fine, but I got some on the magazine tube. Gun started kicking like blue blazes. I set the rings for heavy loads and that helped, but than I realized I had oil on the friction ring. Got me wondering what is best way to lube this properly. I remember reading about something that someone sprayed on his A5 recoil system and let it dry in the warm sunlight and he thought it worked well. Don't recall what it was and figured someone here is bound to have good feedback about the old recoil system.
