I have a like new ATI top folding shotgun stock like this one: http://www.atigunstocks.com/p-99-top-folding-stock-with-pistol-grip.aspx . Currently it is mounted to my 870, but I have the factory adapters for 12/20GA Mossberg 500/590, Remington 870, Winchester 1200/ 1300 & Maverick 88. It also includes the shell holder. I have never fired with it on. I would like to get $50 shipped to CONUS, add 3% for PayPal. These are take-offs from a new 870, never been used. I will include the mounting bolt for the stock. $40 shipped CONUS, add 3% for PayPal. Thanks! I have 3 mag base plates (not the pinky extension ones) for a PF-9. How about $3 shipped FREE to CONUS? Also have a few AR-15 parts. Carbine length hand guards, grip, and A2 carry handle rail. $30 shipped for all!
