It fits a Lon Horiuchi HS stock
It would bolt right up but you still need hardware, as reusing swivel studs renders it pointless as an attachment point, also with minimal thread engagement to internal aluminum block in the HS Precision stock. I ended up buying $17 worth of hardware to use a total of 2x screws to bolt it up, so I have 48 extra on the bench. Ill be putting them on eBay in pairs for cheap to save others the hassle. Otherwise, nice part. Fit and Finish is very nice. Allows me to use a 1913 pic rail bipod on multiple platforms.
