Hello guys,
I'll show you how to make an easy knex shotgun.
with a pump-action system, so you can reload very easy
and fast !!

- it shoots about 50 ft !
- the magazine holds 20 rounds
- you can reload the magazine in 70 seconds
- you can shoot very fast !! (the whole magazine in less than 40 seconds)
- ...


Step 1: The Barrel

Picture of the Barrel

the barrel is not necessary, it is just for make it look cool

1) make 1 of this
2) make this 5 times
3) make this 2 times
4) Add everything together

it a good design
but, i missed out 2 small blue bits and when its under 16 bands on power it just blew up when i shot it ;(
I build it and it shoot like 2 feet

use more rubber bands !
It have max rubber band on.
this happened with me, i was totally gutted, plz fix
yes me too
How many yellow connectors
can you make the part list because i am not sure that i will have it. i dont whant to destroy my gun
I like it. It looks futuristic. I'm gonna build it after I finish my homework.

Does it ever jam/ have reliability issues?
anres321 (author)  StarkIndustries4 years ago
No, this gun almost never blocks and the mag doesnt block either !
the only problem you can have is that the pushpin falls apart if you use to much rubber bands but you can shoot very fast without blocking :p
my fireing pin exploaded: )
anres321 (author)  dragon#13 years ago
yeah, thats a problem you can have with every gun :p just use less rubber bands or add duct tape to the fireing pin to hold the peaces in place
or just dont dryfire
anres321 (author)  dragon#13 years ago
yeah indeed ! if you dont use any ammo your fireing pin wont be slown down and will deconnect.
hahahaha i learned it the hard way
anres321 (author)  dragon#13 years ago
probably the best way !! :p
good gun by the way 5* also could you turn it into a rifle?????????? pleaseÔÔ
anres321 (author)  dragon#13 years ago
how do you mean ? just make it look more like a normal gun ?
shoot 1 peise instead of 3=)
anres321 (author)  dragon#13 years ago
Sorry bro, I really don't have time for this anymore, vacation is just over... It has been a very long time since i have seen my knex :p maybe you can find someone else to do it for you ?
or i could do it
anres321 (author)  dragon#13 years ago
If you do it be sure to post some pictures or something !!
ill do it but i need your permishon
anres321 (author)  dragon#13 years ago
yeah, go ahead !! I would love it if you make it and put some kind of credits in there.
since u made it u will get some credit
also puting the mag sideways like in cod 3 (the old one)
my ammo got jammed so i dont like the gun that much anymore
anres321 (author)  instructaguy3 years ago
do you use the pusher of the mag ? because if you dont use it the impact of the pushpin will cause the ammo to be launched in the mag and they will not be horizontaly anymore
what do you mean by pusher sorry
anres321 (author)  instructaguy3 years ago
I mean the stuff you see in the third picture, step 10. It is used for pushing the bullets down.
sorry read again and yeah i do, i built it twice step by step and i didnt work and i really liked the design.
i made this gun before quiet a while ago and it didnt work. i tried fixing it and i didnt do very well. because it looks so cool and in the video it is so awesome(best gun ive honestly seen). before when itried to build it i did it on my phone but i have a netbook now so hopefully it will be easier, and will work. cool gun man im gunna subscribe, and hopefully it will work.
i just finnished rebuilding this gun and i am gonna use it on youtube
anres321 (author)  knexinventer3 years ago
did you actually use this gun on youtube ? if so, plz send me the link
anres321 (author)  knexinventer3 years ago
Awesome !! great to see one of my guns on youtube !
anres321 (author)  knexinventer4 years ago
Great !! send me a message if you have uploaded it :p

anres321 (author)  knexinventer4 years ago
after a while I did just the same thing with my gun :p I needed some pieces of the barrel so I also shortened the barrel :p
This is cool great instructable
