Introduction: Pump-action Knex Gun

Picture of Pump-action Knex Gun

This is a pretty basic knex gun with a new magazine. It has ok power - I got it to shoot 30 feet with one rubberband. This is my first instructable, so please go easy. Enjoy!

Step 1: The Body

This is the body of the gun. That's 28 spacers in the middle there.

Step 2: The Pump/ramrod

Step 3: The Magazine

Step 6: Loading and Firing

Load four blue rods into the magazine of the gun. Pump the gun, pulling back the ram and pop the block into place. Pull the trigger at the side of the gun to fire! Look at pics for rubberband placement, though you could pretty much put the rubberbands anywhere.

A little word of advice, don't ask for people to be nice because it's your first instructable. It's not considered to be a valid reason for bad things ( Not saying this is bad! ) The instructions and pictures are both clear, and it's not a stupid Killerk copy. The gun itself is not bad, but pump actions with trigger are better in my opinion. Certainly not bad for your first instructable. Wish I had a decent camera ;)

mythbusterma (author)Dutchj2008-07-04

no offence or anything but i think it has a trigger idk

Not exactly a true trigger, it's the kind on the side of the gun that you push with your thumb.

DrWeird117 (author)Oompa-Loompa2008-09-12

A block trigger.

Oompa-Loompa (author)DrWeird1172008-09-13

Yeah, pretty much. But we'll call it an "advanced" block trigger, LoL.

Bartboy (author)Oompa-Loompa2008-09-15

no no no, I know what an advanced block trigger is, it is much better and stronger

DrWeird117 (author)Oompa-Loompa2008-09-16

It was 12 pounds, impractical, jammed, didn't work very well...Need I say more?

Oompa-Loompa (author)DrWeird1172008-09-16

Aw, 12 friggin pounds of malfunctioning child construction plastics eh?

DrWeird117 (author)Oompa-Loompa2008-09-20

CHILD construction plastic? There's 50-year olds that "play" with K'nex.

Oompa-Loompa (author)DrWeird1172008-09-20

DrWeird117 (author)Wafflicious2008-12-10

WHOO! But the speed sensor was fixed. There's a really good buffet on Snow Road in Parma Ohio, near where I live! Where do you live?

 There are many and i usually steer clear and stay in parma Heights
i live like literally a couple blocks down from pearl and snow ... just across from halcyon

Whats up homie

Holy crap, that's pretty close. Snow and Pearl? They have a good Chinese buffet on Snow.

DrWeird117 (author)ILIKEPIE3332009-01-21

DrWeird117 (author)ILIKEPIE3332009-01-25

ILIKEPIE333 (author)DrWeird1172009-01-26


DrWeird117 (author)ILIKEPIE3332009-01-27

ILIKEPIE333 (author)DrWeird1172009-01-27

DrWeird117 (author)ILIKEPIE3332009-01-27

Y--No. Tell ya what. Google "Hell Town, Ohio".

ILIKEPIE333 (author)DrWeird1172009-01-27


ILIKEPIE333 (author)DrWeird1172009-01-27

I know, I saw it The Wooster I found was in Ohio

Sadly I live in Holland, but I will later go living in America or something like that. Holland is BORING. No hills, or rivers, nothing but cold, flat land.

Ooh. But during the winter, it's like that.

maid63 (author)DrWeird1172009-01-21

what is it like in holland ive always wanted to go there.

DrWeird117 (author)maid632009-01-24


maid63 (author)DrWeird1172009-01-26

yeah but i didn't feel like posting it, it was too flimsy and whenever you set it down it snapped in half

Yeah, it's quite good, the dunes are VERY nice, and the sea is also beautiful, but in the winter it is HORRIBLE. No snow, just cold weather and rain. Also there are no mountains at all. It is, except for the dunes, flat land.

sounds cool i live in america i may go there on vacation someday

DrWeird117 (author)maid632009-01-21

I don"t know> I"m in America>

Except for the dunes, but that is the only nice landscape.
