Try listening to the "party line" 9am - 11am ; Mon.- Sat. on WBTG - AM 1290, - Call in to Buy/Sell/Trade items; 256-383-1290: Frequently you will hear people looking to buy/sell various firearms . Hunting season is approaching. Also I believe you can mail in your items you want to sell and Host Don McGee will announce it over the air.
Good Luck
