This gun combines the power of a bow with the reliability of a rail gun/slingshot and the size of a bullpup.
To be honest this just started out as a cannon but I realized that there has to be a more compact way to do it. The mass of rubber bands at the back give tension like bow arms but use much less space. The long bands stretch until a certain point then they pull the "bow arms" bands and create a huge amount of tension on the trigger (my own design that has never broken EVER) that can then be released to shoot the ammo at crazy ranges for something this size.
Range 90-100 ft depending on ammo and bands
Very accurate to about 30-35 ft then you need to arc the round
Rof depends on user but i got about 8-10 rpm on my trials
DISCLAIMER don't be an idiot don't shoot your friends shoot your bother instead
DISCLAIMER 2 this gun CAN AND WILL break SKIN only shoot at siblings (or maybe that pesky cat or that girlfriend that you just can't dump) not friends
My ammo choices
Note all ammo must have a red 3 slot connector or grey 2 slot connected attached to the rear
NOT OODAMMO it doesn't fit the barrel without modifications
YES it is UGLY but it is just a PROTOTYPE and will have more versions made
