I've heard about magpul BAD, but am interested in the troy industries one. I want to manipulate the lever with my left trigger finger, since I am left handed. I don't see that the magpul version offers the option of manipulation with the left finger. Has anyone heard or use this version. I would love to see pictures. I want to install a norgon ambi catch as well so I can truely have an ambi AR, I want fast tac reloads too, its not just right handed territory!
