I was thinking of installing some swivel cups for quick detachable swivels on a laminate stock. My plan was to drill a recess in the stock and epoxy them in place. I have found them for sale on amazon.ca but they are $29 but they want $31 shipping. Has anyone done this and/or know of a reasably priced source for such parts? I see they are made by Uncle Mikes and several specialty outifts, for sale in several Americal sites but nothing in Canada. If only Brownells shipped here.
