  4. High Tech, Low Cost: Minman Intrigues with STEN Lower and Spud Gun

Minman Firearms & Manufacturing is another innovative company we found at the Vanguard booth during SHOT Show 2026. 

Minman is an additive manufacturer of firearms – additive manufacturing essentially meaning 3D printing. Minman is using the most advanced processes to manufacture firearm solutions for several designs. 


STEN Lower

Check that Apple Fritter, tastes good.


Minman offers a 3D-printed lower for 9mm-style upper receivers. This lower feeds from cheap, readily available STEN-pattern magazines, allowing the user to pair an inexpensive lower and magazine type with a modern production PCC/sub-gun upper, keeping the platform very affordable. 

Spud Gun
 

The Spud Gun uses popular 37mm rounds. With the proper paperwork and ATF approval, this can also be changed to a 40mm tube, for those who have the proper licensing.


Minman also has an innovative 3D-printed 37mm flare launcher that looks something like the M320 grenade launcher. Although 37mm launchers are popular, they can be pricey. Minman makes an affordable launcher that can be upgraded to a 40mm tube with the proper paperwork and approval from the ATF. This allows folks to enjoy launchers at a fraction of the cost of many other options. 

Additive manufacturing is the way of the future, and it is exciting to see companies innovating designs that make things more affordable. 
 

The spud gun, just like the name, seems like a lot of fun.
