First appearing in 2018, the Mech M1 mechanical force feed hopper is an oddity in the paintball world. Unlike its battery powered competition, the M1 uses a spring winder to operate. The most unique feature of this hopper is the Archimedes screw feed mechanism.
The M1 can feed at a rate of 11+ bps but does generate quite a lot of noise in full flight. Overall whilst an ingenious product, I think the M1 is a solution looking for a problem. Still it rates 11 out of 10 on the geek meter in my opinion.
