Benelli LUPO .300 Win Mag 4 Round Magazine. Made from strong polymer and designed to seamlessly integrate with the Benelli LUPO geometry, this detachable box-type mag accepts .300 Win Mag ammunition. This rifle magazine has a 4 round capacity and mimics the same rugged / lightweight form of the LUPO rifle. Great as a spare or to replace a worn mag, you can expect the same Benelli quality from this magazine as you would from the original that came with the rifle.
