Awesome gun! But in my opinion there needs to be a different ammo mag than a hopper. My ammo always falls out if I'm not careful. Other than that it's an overall great gun!

You must have built it wrong. Please don't capitalize your comments because it shows an agressive and un-nice tone.

Look. First of all, I'm entitled to an opinion. Second, it's not flagged. Third, I think about three or four times building it is enough to prove that this gun is a fail and people who do get it to work apparently have to put it through some changes. I rest my case there.

 I'm going to save you the hassle and tell you right now- the last step is impossible to build.  Instructions are terrible.  Just move on to another gun.  Do NOT build this gun.  

author
brownfamily52 made it! (author)2010-01-13

I think you should revise your instructions because they either are blurry, out of order, impossible to tell what to do, or just plain wrong.  This looks like a good gun, I just wish you would take some time to make this better.

If you put a rubber around the firing pin it souldnt break.
the man that made it has a website with it on and he called it pum action p90 shotgun  lol
here is the link====http://knexinstructions.weebly.com/pump-action-p90.html
you can get a 2 barrel shotgun that holds 14 bullets and claim to fire atleast 16 metres

author
koolkidd made it! (author)koolkidd2009-07-06

you can use spacers, tan connectors, or metallic blue connectors in some places.

sorry to say, but tan rods ARE NOT strengthened red rods. they are just a different color

author
koolkidd made it! (author)koolkidd2009-07-06

they ARE. bend a red one. bend a tan one. you need a lot more force to bend the tan one.

author
NYPA made it! (author)2009-07-06

author
Opposite Skunk made it! (author)2009-06-05

Smooth design, always works, but it's not very powerful... Maybe I should add some more elastics...

author
NYPA made it! (author)NYPA2009-07-06

author
NYPA made it! (author)2009-07-06

author
NYPA made it! (author)2009-07-05
