*** SOLD!! *** For sale is a lightly used Short Lane 12 gauge to 20 gauge smooth bore adapter. Will work with most shotguns (save for semi autos). Works best with break-barrel, but will work in pumps. Simply slip your cartridge in the adapter and load it in the chamber and you're ready to go. Price is $20 cash, FTF in the Portland/Vancouver Metro area. I've got a partial box (14) of 20-gauge bird shot shells I'll throw in with the adapter. If you're interested, please PM me (Conversation) here on the forum.
