After collaborating with Mauser, John Rigby & Co. developed the Rigby Big Game. This Single Square Bridge .375 H& H rifle features a grade 6 wood stock, Magnum Mauser action, three-position flag safety, London proof marks just like the originals. Designed for professional hunters, the single square bridge is only designed for use with express sights. Other features include a higher comb to absorb recoil, plasma nitriding to reduce glare and rust, hand-engraved finishing touches, case-hardened recoil bars, and a heat-blued extractor.
