 This is a highly advanced gun, it takes alot of skill to build and use it, unless you are a knexer. And you know who you are. TO sum it up, this gun is more advanced than other guns and it is not recommended for newer builders or even moderate builders. This is an advanced gun.

Lol, Knextion. Make the connection of the handle with the dual barrel.

EPIC but i made the grip even more comfy and came up with mag
pushers because it wasn't clear on how to put the bands on the mag.

p.s. to mag even more comfy take off the big wheel and put to more little ones

epicbobman52 (author)2010-11-27

aheyn (author)epicbobman522011-11-17

KnexFreek (author)epicbobman522011-04-08

might b hard

~KnexBuild~ (author)2011-10-18

awesome. 5*

DracoUltima (author)2011-05-03

Hmmmmm.....are the dual mags solidly attached to the gun? The way I see it, the mags could easily be plopped off.....

Football viking boy (author)2011-04-30

Where does the rubberband for the mag hook up?

look up sergant gumdrops knex gun on youtube. This will answer all mag and band questions.

can you post the movie because my parents restricted youtube... and all other sites besides instructables and webkinz(for my sister)

Fred the Penguin (author)2009-11-16

I don't see how it would fire individually from the photo, you should band individually

yes i know! but i like shotgun shooting!

in the pics it is banded so it will fire like a shotgun only. I will take pics of them banded separately soon
