This is the 4 round .308 magazine for the Browning Maral.
Also fits the Winchester SXR2 which shares the format.
Made from blued steel this factory replacement magazine is a double stack design.
For use with the Maral hinged floorplate part B3178012AA.
If you want spare magazines ready to go, you will need the hinged floorplate as well as the magazine, as in practice clipping and unclipping mags into the floorplate in the field is fiddly and really needs tools.
