I have a cz 527 wood stock which has a crack at the front top forestock. The barrel is fully floated with the stock standing off the barrel a full 3/16" at the end of the forestock. The crack is completely through the stock laterally and progressed about 1 1/2" back. The cracked portion of the stock has not yet detached but as the crack works back and up with the grain it will detach. Any suggestions on repairing would be appreciated.
