Better sling swivel than bipod adapter - Vism M-LOK Sling Swivel Stud/Bipod Adapter

This m-lok design takes up 1 & a half slots due to its length and locking "ears" do not rotate, but clamp onto ends of slots. Unit is constructed of steel, making it very strong, but heavy. The swivel works well for slings, but my bi-pod could not be completely stationary no matter how tight it was adjusted. Considering applying epoxy to swivel to add stability.
Neutral on recommendation.
