The detachable box magazine is a double-stack configuration with a partial divider that loads like a single stack. Cartridges can be easily loaded with the magazine removed, or smoothly top loaded with the magazine in place, holding 5 rounds without heavy spring pressure. The LUPO cutaway bolt works with the magazine, allowing the magazine to insert fully into the receiver without protruding from the bottom of the gun80322: Benelli Magazines 243 Win, 308, 6.5 Creedmoor80336: Benelli Magazines 3006, 270W,80337: Benelli Magazines 300WM
