I've got an 1894, and where the rubber end of the butt of the stock attaches to the black composite line at the very end of the wood, it got hit or something and the rubber piece has a hairine crack/tear just at one end. it's more than hairline(maybe 1/16th") - maybe 1" long(down the black line at the end of the wood). What's the best way to glue/re-attach that so it's less noticable? Thanks.
