Mech M1 Wind Up Hopper
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.
