I thought I would mount a short pic rail to the front of the FX soft touch stock to mount an extended rail under the bottle. The stock is curved at the bottom and somewhat thin. So not designed to mount a rail to. I took a short rail meant to be mounted by M-lock and ground the bottom to fit the curve of the stock and then drilled two holes and used two furniture nuts on the opposite side . The FX synthetic stock material is like a dense styrofoam material and very soft and flexible. I would advise people to not go this route but instead use a bottle mount. Any way here’s my set up which I’m happy with as the fore arm grip touches the bottle and helps to strengthen the forward rail with bipod. At first when I got the rifle I questioned why FX didn’t add some material to the forward end to make it easier to mount a mounting rail but now I know why. Now if they would only make a walnut version.
