I run a T6A with mini chassis and was too cheap / didn't plan for eventually running an Atlas when I ordered mine from Manners. So I got an Area 419 picatinny bipod mount, it came with the screws and Tee nuts. A few minutes of drilling on a drill press, plus some epoxy and BAM good to go. Its not hard at all, once you get over the nervousness of attacking a new stock with a drill bit.
