Check with Todd Grove at ohiorapidfire.com
He was clearing out the last ones he had. A guy he had sold several to was posting them for sale at Subguns.com in the under $500 free ad page. Todd's one of the good guys, so don't worry about him or any deal you do with him.
He's also an FFL C2/C7. Tell him Larry referred you.
William from the Tannery Shop also offers 80%'ers in various grades. He usually posts here on the want to sell page.
Hope this helps some. loose-round
