Technical Definitions

The firearm, excluding the barrel, is constructed largely of a rynite plastic in order to reduce weight. It features a bullpup layout to preserve a 525 mm barrel length in an overall 787 mm package. The shotgun is fed by a 10-round capacity center-rotating drum using conventional 12-gauge cartridges. The shotgun weighs 4.57 kg and has a maximum rate of fire of 240 rpm. The drum's method of rotation is very similar to the Webley-Fosbery Semi-automatic revolver.

The floating barrel is driven forward by gas pressure from the fired round. The barrel is then returned by a spring and moves the drum operating rod, breaking the tight seal between the barrel and the drum to revolve. Spent cartridges are not ejected. Instead, they remain in the magazine.

Famous quotes containing the words technical and/or definitions:

    I rather think the cinema will die. Look at the energy being exerted to revive it—yesterday it was color, today three dimensions. I don’t give it forty years more. Witness the decline of conversation. Only the Irish have remained incomparable conversationalists, maybe because technical progress has passed them by.
    Orson Welles (1915–1984)

    The loosening, for some people, of rigid role definitions for men and women has shown that dads can be great at calming babies—if they take the time and make the effort to learn how. It’s that time and effort that not only teaches the dad how to calm the babies, but also turns him into a parent, just as the time and effort the mother puts into the babies turns her into a parent.
    Pamela Patrick Novotny (20th century)
