I run a 11-87 I had dipped in Realtree AP with a 23 inch tube and an X-full choke, cant recall the maker, high viz sights with a monte carlo stock.
Not a super custom by any means but one I put together the way I wanted it. Shoots gobbler dumpin paterns to 40+, although I hate to shoot much past 35 or so. To me its a game of getting them close, not how far can I shoot one.
