The Close Support Weapon System was an Australian family of firearms designed by Duncan Gordon in 1970, consisting of an assault rifle , shotgun , assault shotgun , light machine gun and a twin-barreled submachine gun .
Development [ ] This very unusual family of close- to mid-range automatic weapons was proposed in the 1960s by Duncan Gordon. It is assumed that this family of weapons constitute a belt-fed shotgun, automatic shotgun with a box magazine, battle rifle, assault rifle and a double-barreled submachine gun with overhead inserted magazines (à la the Villar Perosa ) in a very unusual configuration. Gordon has developed his weapons, based on personal combat experience he gained in Vietnam serving in the forces of SEATO.
Design drawings and the general conception of his ideas involved in the Australian company BSP Planning and Design Pty. Ltd. in Norwood. Work began on the weapon in early 1970, with Peter Chant leading the team of engineers behind the weapon. The system was developed by 1972, and drawings were submitted by accomplished engineer Dale Evans. This system was a weapon with a quick-change barrel, while the overall configuration had a mixture of ideas from the British EM-2 , as well as World War II-era platforms such as the German FG 42 and the American Johnson light machine gun , with every weapon configured to be able to 7.62 NATO, 5.56 NATO, 9mm Parabellum and 12 gauge rounds with modifications.
No physical prototypes, whether they be either non-functioning mockups or actual functioning ones, appear to have been produced; very few records of the CSWS' development appear to have survived.
Variants [ ] Combat shotgun - Variant fed from a side-mounted box magazine.Belt-fed shotgun - Self-explanatory.Assault rifle - Variant fed from a side-mounted 30-round magazine.Light machine gun - Variant equipped with a heavy barrel, bipod, and fed from a side-mounted 30-round magazine.Submachine gun - Variant with two barrels, side-mounted grips, top-mounted magazines and a folding stock.Gallery [ ]
