The Neal submachine gun was an American conceptual rotary submachine gun designed by Ernest Neal. It was fed from a helical magazine inserted into the weapon from the rear.
History[]
The concept of this weapon was to overcome the deficiencies of the low power rimfire cartridge by rapidly delivering a large number of projectiles. The weapon therefore relied on the .22 LR's very low recoil and a high rate of fire of 3,000 rounds per minute, rendering it theoretically able to empty its entire magazine in one second. It lacked a stock, but instead had a rear grip on the left side and an arm rest to handle the recoil force when firing.
The Neal did not appear to have gone beyond the blueprint stage, so no functioning prototypes, or even a mockup, were ever made.
Design details[]
The Neal submachine gun's design was intended to reduce barrel erosion and overheating, enabling long periods of sustained fire. Although it may appear so, it is not related to the Gatling Gun's action, rather having its roots in the similarly operated Webley Fosbery automatic revolver, using a cylinder operating surface that interfaces with a single bolt to rotate the barrel cluster.
