Just got a S&W performance center .460 with 14" barrel. It came with a sling , bipod and sling mount swivel adapter. can anyone tell me how to mount both the bipod and swivel mount for the sling? Directions were not there and while I don't think I am dumb I can't figure it out. Can both be mounted or do you have to choose one or the other? The bipod and swivel stud kit that came with it are both UTG;s and also included a yhm dovetail sling mount. thanks for the help.
