History[edit | edit source]
In the early 1940s, Russel Robinson designed a "constant recoil" machine pistol known as the SR-11. It was tested against the STEN Mk V and the MCEM-2 in trials conducted by Maj. Eric Hall of the United Kingdom Ordnance Board. The SR-11 was deemed to be significantly more accurate in fully automatic fire compared to the other two weapons, but not as much in semi-automatic fire; as such, the Ordnance Board recommended Robinson to redesign the SR-11 so that it would be accurate in semi-automatic fire while still retaining its accuracy in fully-automatic fire.
What would become of this would be known as the SR-16, which featured some major design changes compared to the SR-11, such as a forward-placed sear and a conventional firing pin. However, apart from some firing fixtures, no complete SR-16 was ever built. No subsequent attempt was made to build the SR-16 as by then there was no requirement for any more automatic weapons in the United Kingdom due to the adoption of the Patchett gun and with Russell moving to the United States.

As the weapon was essentially a further development of the SR-11, the basic action would have been practically the same, featuring an auto-ejecting magazine and a free-floating rotating barrel. However, it would have featured a conventional firing pin and a forward-placed sear. The weapon would have been fed from 16-round magazines.
