Introduction: Pocket Rifle (Knex Pistol)

Picture of Pocket Rifle (Knex Pistol)

Description: This is a high power knex pistol that will fit into your average front pocket. It has very good accuracy over a long range but shoots high so you need to aim low. it is approximately the same size as KILLERK's pistol but is (debatebly) more powerful and can fire any size rod (yellow rods work best) and can even fire twigs from trees, laugh out loud. The gun is very sturdy and the firing pin is difficult to remove from the back so that it is less likely to be accidentally pulled out during cocking. It is single shot, the trigger rotates clockwise to fire. It uses one cut part for the trigger (half a green rod) and duct tape on the firing rod pull. It uses firing elastics, a trigger elastic, and three elastics to keep three white rods in for extra stability.

You need a k'nex hinge to make this gun.

Step 1: Build

Picture of Build

1: Build 2 of these.
2: Attach with 8 white rods as shown.
3: Make this.
4: Attach by connecting a white rod on either end as shown.
5: Add 3 white rods as shown. Pull an elastic from one end of the rod, over the top of the barrel, to the other end of the rod. Now each elastic keeps the rods from falling out of the holes. Refer to picture 16.
6: Make this (the green rod has been cut in half).
7: This is what the fully assembled trigger will look like when it is in the gun.
8: Add the trigger. Attach elastic as shown.
9: Make this.
10: Attach as noted.
11: Hold a gray connector pointing up like this.
12: Attach as noted.
13: Make this.
14: Add duct tape as shown.
15: Insert into gun. Add firing elastics as shown.

Step 2: Firing

Picture of Firing

1: Lightly pull back on the trigger as shown while pulling the firing rod back.
2,3: Load a rod.
4: Push the trigger down and forward (clockwise) with your thumb to fire.

How does the trigger attach?

mweatherl (author)2011-09-29

Hey Oblivitus, this gun is one of the first ones i made, but i found out that using the big grey rod with good rubber bands make the rod bend, and also when it fires, the orange connector snaps out of place. What i did to fix these problems was not use the orange connector at all, and i use a smaller rod. Now i can use better rubber bands!
This gun is awesome, please post more!!!! :)

this nick is invalid (author)2011-07-21

same here. i haven't got enough pieces and i've built knex gun builder's pocket pistol and then said "omg. this guy is a weapon engineer.". it's very powerful, it has a true trigger and a mag(not removable). but when i put lots of rubberbands to hold teh ram, it brokes -_-.

Twister802 (author)2009-12-03

dude what does the broken peice do??

Oblivitus (author)Twister8022009-12-03

It allows you to put lots of elastics on the firing rod by preventing the hinge from collapsing.

asdfda3432 (author)2009-05-20

Is the green rod in step 7 supossed to be cut in half or is it just the picture???

Oblivitus (author)asdfda34322009-05-20

Yes, it is supposed to be cut in half, it will take a while to saw through one with scissors.

mettaurlover (author)Oblivitus2009-06-22

i just set mine on fire. it's melty, but it cuts like butter.

Sandy44444 (author)mettaurlover2009-08-31

KnexFreek (author)Oblivitus2009-12-01

mettaurlover (author)KnexFreek2009-12-01

we're ALL crazy here, JSYK.

mettaurlover (author)Sandy444442009-08-31

no "real" trigger?!? all you do is put a white rod in the grey connector and you've got a real trigger.

Oblivitus (author)mettaurlover2009-06-23

LOL, nice.

mettaurlover (author)Oblivitus2009-06-23

k'nex are surprisingly flammable. they'll burn like a toxic candle.

asdfda3432 (author)Oblivitus2009-05-21

dang! that gunna be hard! thx 4 answering

Oblivitus (author)asdfda34322009-05-21

It is, but if that is too hard for you, then you can snap the end off of a longer rod instead.

asdfda3432 (author)Oblivitus2009-05-21

o thx :D il try that i already have a broken rod i just broke by accident :P

Oblivitus (author)asdfda34322009-05-22

I have around one hundred or so broken parts, most of which were broken accidentally. XD

asdfda3432 (author)Oblivitus2009-05-23

lol i have broken connectors too :P

Llamaboy419 (author)asdfda34322009-11-15

I have like 5 broken orange connectors. It's pretty sad. I also cut orange connectors in half rather than clipping greys. Two out of one connector.

asdfda3432 (author)Oblivitus2009-05-23

o wow.

KnexFreek (author)Oblivitus2009-09-16

wire cutters

Oblivitus (author)Oblivitus2009-05-20

By the way, be careful cutting! Don't stab your hand because I did that once and it bled badly.

advinator (author)2009-12-01
do you use google sketchup for your 3d modeling?
Oblivitus (author)advinator2009-12-01

No, I use mlcad.

dudemanvango (author)2009-11-29

could there be subsitute for the broken rod. cause i cant break it.

Oblivitus (author)dudemanvango2009-11-29


dudemanvango (author)2009-11-29

you can make a scope by switching the white rods in the 4th step with blue rods adding a y connector making a right angle down from the blue rod and adding a gray end connector.

dudemanvango (author)2009-11-29

for #2 are the white rods needed.

dudemanvango (author)2009-11-29

nice gun. it simple yet powerful. i would like some thing like this but more powerful.

knexjay (author)2009-09-23

same ram as z35 (best gun ever because of chamber)

Oblivitus (author)knexjay2009-09-23

Yes, this is my signature firing rod. And thank you, what is it that you like about the Z35 chamber?

cj81499 (author)2009-09-04

doo you need to break the piece?

cj81499 (author)cj814992009-09-04

sorry do

bigdylan91 (author)2009-08-18

I was wondering instead of cutting the green rod in half could we just use a y clip with the two sides broke off? I'm going to try it first.

Oblivitus (author)bigdylan912009-08-18

Yeah, you probably could.

DJ Radio (author)2009-06-29

This gun is pretty underrated.

Oblivitus (author)DJ Radio2009-06-30

Thanks, I know, it is way under rated. I think the problem is that no one has actually built it or payed any attention to it. It has the same range as the DD-27 and it can be dual wielded by making a left and right handed one just by flipping the trigger from one side to the other. I was expecting at least a 3.5 rating, there are noob tube guns that have a higher rating than this.

DJ Radio (author)Oblivitus2009-07-10

the only 2 noob tube guns that I can think of that are rated higher than this are (your name here)'s basic knex cannon (highest rated noob tube gun), and killerk's first pistol.

Oblivitus (author)DJ Radio2009-07-11


knex_mepalm (author)Oblivitus2009-08-10

I made it too!!! IT was an awesome gun, it shot pretty far but the trigger jams a bit when i pull the firing rod back, any idea how to sotp that? otherwise, great gun 4.5*!!

Oblivitus (author)knex_mepalm2009-08-10

Thanks, and there is no way to stop that, I made a mod to this since I posted it that you might want to try too, I tied a string from the trigger to the bottom of the handle, so that when it falls off, you won't lose it.
