So, the idea is, fit a section of Anschutz rail to the bottom of the chassis, it has the usual threaded mounting holes for picatinny rails so it could screw into a couple of those and then fit the bipod the "normal" way using the supplied rail adaptor and locking screw.
Anyone know where I can get a section of Anschutz rail at a sensible price?
This is the Evo QD adaptor fitted and screwed to part of the Evo bipod, it's very loose as there's a lot of play with the pin through the QD stud hole and free space under the adaptor plate (the black insert)

This is the sort of rail piece I'm looking for (or similar)
