Sportsmen's Den in Shelby, Ohio also has the BT 99 AR's new. They are on sale right now for $1899.00. If I were buying a new BT type gun this would be it. The only trouble with them has been a forend issue, as they work loose. Rod's custom gunshop, also in Shelby, has fixed them. He said it is not an expensive fix IF users don't try at home fixes. I would buy one and take it right to Rod and have him update the gun. I found a minty BT100 or I would be shooting one of the AR's from Shelby right now.
From what I understand, the BT-99 AR was a limited production gun made for Sportsman's Den several years back. It was,is a slow moving gun with the loose fore end issue. Last I knew, they still had some in stock. Clyde
The BT 99 AR was not exclusive to Monsoors. Sportmans Den in Shelby has them in stock and on sale for $1899. Mash the link and see for yourself on page two. I was there on Tuesday and saw them on the rack.
