This gun reached 6th highest rating for knex!!!

Whether you like it or not, here it is.

Because I cannot be bothered typing out a wall of text here is some stuff from my forum topic.

The concept behind The Logic Bow
By using a ratchet system to hold the bands behind the pin you can:
@ Decrease pin friction in barrel
@ Increase pullback distance
@ Increase power
@ Make the pin easier to pullback
@ Have a simple rail system

HOW IT WORKS
This is a pin type gun, not a slingshot. It uses a ratchet system to hold the rubber bands, therefore increasing the amount of bands that can be used and increasing ease of pullback. These bands are released when the trigger is pulled, propelling the pin into the bullet. This means that the effective pullback distance is increased, therefore increasing the range and power.

well here is the first "new thing" I have done in ages, (the last Truly innovative thing I built was the D-Frag grenade) the Logic Bow. It uses an all new 4-stage firing system that runs between two rails (I tried using a dual rail system but that didn't work out). So far I have the mech working, but it needs the rest of the body, the bow, a handle and probably a stock. It is a single shot that should have more power than a pin gun, the really cool thing about it is that although it uses a pin mech the pin takes almost no effort to slide back.

Review by Knex Gun Builder

and how I would rate it.
power 8/10 incredible power for a pin gun
rate of fire 2/10 for single shot version
rate of fire 5/10 for the turreted version, very slow
range 7/10 one of the highest ranged pin guns out there
comfort 7/10 comfy but could be better
innovation 9/10 first gun of its type, but not exactly new (lt licorice)
ease of use 10/10 my sister can use it, nuff said
looks 6/10 not the best looking gun, but fully loaded from the front like in the pics it looks cool
War Rating: I would recomend it for large scale wars because:
-It has a better range than most guns
-It is quite large
-Low rate of fire is really bad in close quaters
overall 8/10 or 4* but rate it whatever you want.

Sorry its all in one chunk, I couldn't be bothered taking it apart, it should be easy enough to build though.

Again I couldn't be bothered to break this up completely, but you should manage.

I did this one properly, you do not need the orange connectors on the z axis, they just add more support.

wow, that was fast

Loading and firing
1 pull back bands onto ratchet, make sure they are at the back.
2 pull back pin
3 stick bullet into front barrel, make sure it is locked into the bullet lock
4 point the gun at whatever you want to die*
5 pull trigger and watch what ever you pointed it at get pwned

*so don't point it at anyone, seriously don't.

Well here's how to turn your Logic Bow into the turreted version. This shows how to mod it into an 8 shot turret but you can just as easily use an 18 shot version by using a black rod on the bottom connector slot.

Bigger, Meaner, Awsomer.

Well after a long string of failed projects I rebuilt the L Bow. But this time I made many improvements to the original design, these include:
-Removing the bottom of the rail to get rid of friction
-Modifying the handle for comfort
-Adding a removable stock
-A more intergrated turret design (the old one looks like it was just stuck on)
-A tactical rail for things like ammo holders or a bipod
-A support rail to add strength.
