<p>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!</p>
Looks cool.
Don't build this, ive built it before and it doesn't even compare to other guns!
ya i can make it now the origanle auther pissed round to much
when the gray rods are added (pic 7) if they r on the 8th connector does it efect the gun
how do u connect the red connectors
&nbsp;Ooooooohhh maaaaan! I remember making this gun a year or so back by use of his pictures... probably best gun I ever made from K'nex (That was had a mag)
&nbsp;How well does it shoot?
&nbsp;Awesome gun! Love it! So Cool and&nbsp;definitely&nbsp;worth it!!!
&nbsp;I'm going to save you the hassle and tell you right now- the last step is impossible to build. &nbsp;Instructions are terrible. &nbsp;Just move on to another gun. &nbsp;Do NOT build this gun. &nbsp;
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. &nbsp;This looks like a good gun, I just wish you would take some time to make this better.
what if i dont have hinges will it work???????????????????????<br />
If you put a rubber around the firing pin it souldnt break.<br /> the man that made it has a website with it on and he called it pum action p90 shotgun&nbsp; lol<br /> here is the link====<a href="http://knexinstructions.weebly.com/pump-action-p90.html">http://knexinstructions.weebly.com/pump-action-p90.html</a><br /> you can get a 2 barrel shotgun that holds 14 bullets and claim to fire atleast 16 metres&nbsp;<br /> here is the link====http://knexinnovation.net/forums/viewtopic.php?f=49&amp;t=149<br /> <br />
&nbsp;its cool but at most mine got 20 feet and even with balanced rubber bands the firing pin kept breaking it works but i just cant get the range maybe my pieces are weak&nbsp;
&nbsp;looks like a p90
probably really far.
How far does it shoot?
i shot it up to 60 ft.
i got 15ft and if you put too many bands on the trigger snaps
you have to balance out the trigger bands too.
hey koolkid, the comment you made back to me sounded so perverted
haha. yeah..
The slide is really comfy!
Awesome, I found that blue and black half hinges yesterday when working on another gun!

Well, duh.
is there a way not to use 60 grey pieces?
you can use spacers, tan connectors, or metallic blue connectors in some places.
see top comment. BURNED!
sorry to say, but tan rods ARE NOT strengthened red rods. they are just a different color
they ARE. bend a red one. bend a tan one. you need a lot more force to bend the tan one.
Smooth design, always works, but it's not very powerful... Maybe I should add some more elastics...
add three. I did that and it goes WAY farther.
or you can use a ball and socket. I used that and i see no difference.
i have all the pieces except for the hinges! i will use ball and socket!
the hinge can be substituted!
i don't have any hinge pieces too. I do have everything else though.
i dont have the hinge thing (the blue or black) is it posible to use something else please reply with a answer!!!!!
rofl
this gun looks like the battle rifle from halo 2
agreed
they are strenghend rods as i have one.
you have 7 pictures not 8
you have 7 pictures not 8
Wow looks amazing!!! How long did it take to make???
few hours.
wow
whats the difference between the tan rod and the red rod? i dont have a tan rod.
tan rods are strengthened red rods. you can just use a red one.
you are very annoying ,but great gun
