I'm making a run of slides from 12 gauge shotgun barrels. If I knew how to post pics here I would, alas I'm clue deficient. These slides are made using only hand tools and due to the bore diameter they typically fit a US ring size 8, which limits them to use on the little finger only, that is unless you've got very small fingers. I'll work with you and get the length you want, so If anyone is interested, contact me at email@example.com for pics and additional details. I'm figuring pricing at $25 per slide shipped, US only. Thanks.
