A Harris BRM-S bipod with a pod loc and Arca adapter works great. The MDT bipod for $200 with Arca looks pretty good if you wanted an Atlas style without the price tag.
For a bag, a Game Changer is an excellent bag to use for a lot of shooting. It’s great on obstacles with the rifle on it and can be used prone as a rear bag. Some use a larger bag in the back when shooting off props but some don’t. The good part is people will let you try them at matches so don’t go out spending hundreds on bags until you try some.
