I added a saftey switch that you cann turn on and off with a little dial.

SUPERB RIFLE! try making the same gun but with a working magazine and a ram. it probably wont be as powerful but it would make it look even more realistic!

actually, scratch that!!, its all about power!!

The Great Knex Warrior (author)2009-11-26

looks quite good!!!
i made a new sniper rifle, didnt have much pieces but:
it has 2 wheels in the stock to give it weight as i didnt have enough pieces. don't know how far it shoots yet but it can shoot through thick cardboard and come out the other side only a small bit slower.

tthomasvd (author)2009-06-05

is that down that that yellow pice what is zoomet in a black round or an blue??

benfoxg (author)tthomasvd2009-06-06

It's a blue.

DIRTRACER39 (author)2008-12-05

I'm sure this is a amazing gun if it can shoot 130 feet, but i can't figure out how to build it, the pictures are to blurry and not descriptive enough, because of that only 3.5*

Try wiping all the condensation off the camera lens and try again. Nice gun though.

awesome! I'm definately building this gun.

Skreetsha (author)2008-08-23

the pictures arent good but the gun looks nice

04bobby1 (author)2008-08-19

Dont be stupid it isnt the best and it isnt a bullet IT IS A ROUND

No, rounds are, a bullet (the projectile) and a cartridge containing an explosive substance (to propel the bullet) and a primer to ignite it. This is a projectile propelled using the contraction of rubber bands. But seeing as it is K'nex it doesn't really matter.

benfoxg (author)04bobby12008-08-19


apples!!!!! (author)benfoxg2008-08-19

It also cant have "zero friction".

benfoxg (author)apples!!!!!2008-08-19

I mean the barrel has no rubbing friction as the ROUND flies over instead of in it. of course it still has wind friction, though.

juneapaluna (author)2008-08-19

Pretty nice, looks like the real thing and the iron sights are really cool, 4.0
