[338LM]

Anyone have a HS Precision LH Model 700 short action stock with the aluminum bedding block, barrel clearance for a varmint barrel contour, and the BDL hinged floorplate/magazinebox/and spring?

If you have just the stock only (no floorplate/magazine box/and spring) I could make it work also.

I'm not sure if this helps, but midway seems to have what you are looking for...

I know you'd need the bottom metal and magazine, but I think those interchange with the rh version.
