I want to replace the swivel stud and mount a picatinny rail so that I can mount an Atlas bipod. I've seen an adapter where the picatinny rail has a hole where the swivel stud protrudes through (no removal of swivel stud required) and one or two screws secures the rail. Please see - https://www.amazon.com/Savage-110BA-.../dp/B013XRSUZS.

I will upload a pic of the bottom of the fore-end soon.

Thanks.
