Gentlemen, Mike says he can do it but Homeland Security wouldn't allow him to send my nephew's barrels back from the US. Apparently anything: a brass bead, spring or latch is a firearm. So Briley is out, too.

I started search in Canada, and one response was: "We don't do it, and wouldn't do it to that good Japanese-made gun. If it's for duck hunting sell it and buy an 870 and have enough left over for years of ammunition."

I forwarded the information to my nephew. He replied that his SKB M/F had always worked well for him and he regretted being influenced by those slick S/As when they became the rage. Thanks everyone.
