I have for your consideration a Rock Island Arms 12 ga single shot.  3" chamber, 20" Vent rib barrel, flip up slug sight, improved cylinder, modified, and full chokes, as well as length adjustable butt stock and factory sling swivels. Also includes super duper custom Amazon elastic shell holder.  Only fired half a dozen rounds or so.  I'd like to see $100 for it, cash on the barrel head.  I'm located right between Palmer and Wasilla.  Thanks for taking a look!
