Swivel as in panning? Or swivel as in cant from side to side?
If it’s the latter, I have a new Harris SBRM 6-9” w/notched legs and KMW PodLoc you can have for $120
If it’s not for hard use, thought I still believe this would likely stand up to it, pick up a UTG Recon 360. About $75 and one of the best cheap bipods I’ve ever used. Believe it or not.
