This is my entry for oblivitus' revolurionary knex gun contest. i'd say im at about 95% complete with it i just want to add a buffer area around the gun so it's less likely to break when it falls. i can give you a really accurate range estimation because i;ve only used 2 strung together #32's which i figure is about the same as 1 #64 but it gets around 30-40 or feet. It's pretty solid feeling i still have to get to nrph so i can toss it of the the 9th story probably on to the grass maybe the cement if i feel confident it won't break i should have a video of this up on either sunday or monday. if you have comments/feed back i'd appreciate it.
