K3 knex pistol. *new* shooting system

K3 is my new knex pistol, it uses a NEW mecanism to prime the gun, instead of pulling back on a firing pin, you simple cock the top slide back. Like a airsoft gun, or a pistol. It does use quite a few pieces... but it is well worth it.

here is a video of it working

This is my favorite gun on instructables but the handle really needs work

The shooting mechanism is VERY inconvenient. I really like the trigger idea though urah03!

nice concept, but keep working. im trying to mod it with a real trigger and a removeable clip... but idk how long that will take...

Raphite2 says: May 25, 2007. 1:43 PM

On a scale of 1/10, this is a 2. Sure, it has a cool look, and you load it differently, but: a) Hard to load. If you pull back to far, the slide and ramrod comes off, whipping you in the hand. Also, you usually have to push the trigger into place. b) Bad range. If you DO manage to load it, it has almost no range, even though it goes straight for the floor and skips a few feet. c) It uses 3 rubber bands. for 3 rubber bands, it should go as far as the Fruit Fly. That thigh shoots far. And you only need 2 bands. This thing, goes nowhere slow. d) High k'nex usage. A good gun only needs a few pieces. This went through all of my semi-circles. Overall, don't build it. Keep the creativity, but troubleshoot BEFORE posting it.

agreed on all, except the last statement. all good guns have true triggers, and many use more pieces. u also forgot to mention that this is a block trigger...

Oompa-Loompa says: Jul 22, 2008. 2:32 PM

you mean so many pieces, and no trigger attached to the block? It does look pretty cool though.

DJ Radio says: Jul 22, 2008. 5:34 PM

yes on both counts

strato96 says: Jul 21, 2008. 9:44 AM
