These OEM magazines are made from strong polymer and designed to seamlessly integrate with the Benelli LUPO geometry. This detachable box-type magazine is available in calibers like .270 Win, .30-06 Springfield and .300 Win Mag. This rifle magazine has a 5 round capacity (4 round in .300 Win Mag) and mimics the same rugged / lightweight form of the LUPO rifle to last a lifetime.
