It is strong on one rubber band and can be made stronger by adding more. It also is small and doesn't use many pieces.

-Doesn't use many pieces

amazing gun and works great with no jams! I would suggest that you clarify where to put the elastic on the orange connector cause it took me almost an hour to figure out where it went :P Im working on a sniper and after reading this 'ible I've decided to use this type of firing mechanism. I'll put credit on mine to you though :)

Can I add a piece count?

Masterdude (author)SN1P3RL0RD2012-10-11

If it is good (correct) then I don't see why you couldn't. Go ahead if you want to.

May I ask whether there is a reason why you posted that image or are you just spamming and advertising you creations here?

that gun is cool and small im trying to buld it with mini knex thx for the instructable

Super Giant Bubbles (author)2009-11-28

dont get how it is suposed to work

When you pull the ram rod back the ammo pusher will push a gray connector into the place where the ram rod was. Then the ram rod will push the ammo up to the trigger where it will stay until you pull the trigger which will make the bullet and ammo be able to accelerate forward and will result in it shooting.

hey, could you please try to make a gun that fires rods for me please. with a magazine, make sure it's small. i you do, i'll surely build it

temp (author)agent47.2009-11-18

you can fit little green rods in the mag.

Batryn (author)agent47.2009-08-07

This can probably fire white connectors as well.

Masterdude (author)agent47.2008-11-26

I'll try to.

stevenh429 (author)2009-09-04

this is the first knex gun with a mag that actually works and uses little peices!!! AWESOME!!!!!!!!!!

976 (author)2009-09-01

hobobob (author)2009-08-18

more detailed of how to connect rubber band to the trigger

mettaurlover (author)2009-08-02

you kidding? inaccurate and shooting two at a time sometimes are pros, not cons. especially in something this small.

DA MASTER (author)mettaurlover2009-08-04

what the heccccccccccccccccccccccccccc IS THAT

runfatboy (author)2009-07-22

no thats just a shadow

lord voldamort (author)2008-11-18

how is 2 bullets at a time bad?

Sometimes it makes one or two of the bullets go off course.

oh i see, thanks for telling me.

It just depends how you think.

Masterdude (author)agent47.2008-11-26

I don't know.

agent47. (author)2008-11-25

you should try to make a gun that can fire rods instead of gray connectors; but anyway, great gun!!!!!!!!!

Masterdude (author)agent47.2008-11-25

I now prefer guns which shoot connectors over guns which shoot rods. Probably because I make them more often.

agent47. (author)2008-11-24

thanx great gun!! it works perfectly now!!!!!!!

mecmac97 (author)2008-11-24

can you retake picture 4? it is very blurry.

agent47. (author)2008-11-23

great gun, but i don't see how to hook the rubber band to the trigger, someone please tell me..........

Masterdude (author)agent47.2008-11-23

You hook the rubber band on the orange connector of the trigger system, go up and back to the firing ram.

DJ Radio (author)2008-11-19

neat gun, and i made awkward designs when i was a beginner, my best known beginner gun shot two bullets at a time, so i didnt post............ note that all my beginner guns were made before SPEC-9 sniper

pls (author)2008-11-18

Lol, small gun with a true trigger!

Masterdude (author)pls2008-11-18

The trigger system is quite good. I used it in many guns at home.

pls (author)Masterdude2008-11-18


I_am_Canadian (author)2008-11-18
