What you own are two mechanical marvels, made to shoot and built to last. But in all seriousness, the two gents who have already responded have given some good advice. The only thing that I would add, is when you reassemble the gun make sure the forearm is fully seated aganist the receiver before tightening the magazine cap. You could damage (crack) the wood if not seated properly. Cap should be very snug. Tighten by hand, do NOT use a wrench.
