Weapon Wiki

The Neal submachine gun is a .22 LR submachine gun patented under 2,436,175 during World War II. The weapon is unusual as it has 5 rotating barrels. It is fed from a helical magazine inserted in the rear.


The original usage doctrine of the Neal submachine gun was based on the strategy of agile hit-and-run tactics rather than suppressive fire from a strong position. The concept of this weapon is to overcome the deficiencies of the low power rimfire cartridge by rapidly delivering a large number of projectiles. The weapon therefore relies on the .22 LR's very low recoil and a high rate of fire of 3,000 RPM. It lacks a stock but instead has a rear grip on the left side and an arm rest to handle the recoil force when firing.

Design details[]

Early concept of a rotary barrel general purpose machine gun (Circa 2006). The Neal submachine gun operates in a similar way.

The Neal submachine gun is an unusual firearm, 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 but rather more to a submachine gun that changes its barrels for each shot. Its operation has its roots in the similarly operated Webley Fosbery automatic revolver as the bolt recoils against grooves that rotates the barrel cluster.
