author
StarkIndustries (author)2010-10-31

I like it. It looks futuristic. I'm gonna build it after I finish my homework.

Does it ever jam/ have reliability issues?

author
anres321 (author)StarkIndustries2010-11-01

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

author
dragon#1 (author)anres3212011-12-09

my fireing pin exploaded: )

author
anres321 (author)dragon#12011-12-10

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

author
dragon#1 (author)anres3212011-12-17

or just dont dryfire

author
anres321 (author)dragon#12011-12-18

yeah indeed ! if you dont use any ammo your fireing pin wont be slown down and will deconnect.

author
dragon#1 (author)anres3212012-01-06

anres321 (author)dragon#12012-01-07

author
dragon#1 (author)anres3212012-01-08

also puting the mag sideways like in cod 3 (the old one)

author
instructaguy (author)anres3212012-01-16

my ammo got jammed so i dont like the gun that much anymore

author
anres321 (author)instructaguy2012-01-16

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

author
instructaguy (author)anres3212012-01-18

what do you mean by pusher sorry

author
anres321 (author)instructaguy2012-01-19

I mean the stuff you see in the third picture, step 10. It is used for pushing the bullets down.

author
instructaguy (author)anres3212012-01-18

sorry read again and yeah i do, i built it twice step by step and i didnt work and i really liked the design.

author
instructaguy (author)2012-01-15

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'm gonna buy more knex but all I have to spent is £20.
Where would you reccommend buying knex?
The actual knex store (www.knex.co.uk), Amazon or any other sites (I don't trus Ebay)?

author
anres321 (author)killersir7512011-08-01

Sorry for the late response,, I didn't saw this comment :p Actually I didn't bought the last 8 years,, I have so much knex that I've never had the problem of having not enough knex to built somthing. I would buy it on ebay but maybe you can find other websites and try to contact someone personally. you can always try to put a question on instructables,, maybe there is someone on instructables who wants to sell you some knex :p

Please, someone help me.
I built the entire gun except for the barrel.
And when I put one bullet in, it shoots fine. But when I but a couple bullets in the mag, nothing shoots. I have tried it with and without the part that pushes the bullet down. Some help would be appreciated.

author
anres321 (author)ronaldoman1232011-04-09

it could be that your 'pushpin' is not totaly straight and pushes 2 bullets at the same time, so the opening will not be big enoug for 2 bullets at the same time

author
ronaldoman123 (author)anres3212011-04-10

Ill Try

author

Its a shotgun it's supposed to shoot more than 1 shot

author
ronaldoman123 (author)anres3212011-04-10

Thanks, One Thing though.
When i pull BACK the pushpin, the mag drops 2 Bullets in.
So I do not think it is the pushpin.
Any other ideas?

author
anres321 (author)ronaldoman1232011-04-11

sorry I dont know what is :(
I have never had problems with this gun.
maybe you made a mistake
