Introduction: Extreme Builder's Knex Sidearm

Picture of Extreme Builder's Knex Sidearm
hey everyone its me again and this is my new and updated knex sidearm. Its a brand new design and works great. I like the handle more then any other knex gun handle iv felt. Anyways its a great gun with good power 30 feet average and up to around 50 feet. It has a 5 shot mag and has never jammed. Dont be afraid to put ALOT of rubber bands on the pusher. I'll stop talking and you guys start building.

new design
good power
easy to use
mag never jams
slot in the handle for mag pusher
strong frame so load up those rubber bands

complicating for a hand gun
uses a good amount of pieces
uses some of the rarer pieces
trigger isnt far back so reduces power

please rate and comment

It looks great!

I made this gun, and it's ok. The only problem I have with it, is that when I use the mag, (shooting grey clips) the ram shoots the front wall of the mag (the orange connector, green rod, and ball socket) with the grey clip. So I don't use the mag. Instead, I put a blue rod in the barrel and shoot that, and it works just as fine. Overall, this gun is awesome, because of how powerful it is.

Alright, I found a fix so I actually can use the mag. I switched the front ball socket with a blue clip, so there is a little more space for the grey connector. Now I can use it the right way! XD

numm numm (author)2009-12-06

Hey man-
I built your 12 shot knex gun but didnt really like it but i still thought it was a great gun because-
1.)I could actually build it with the limited number of peices i had
2.)The cocking mechanism was great
but it jammed a lot and i couldnt load more than 3 bullets in at a time.

on the other hane this gun is amazing.  although the beginning building is difficult it uses very little peices, is very sturdy, easy to build, shoots great, and is probably the best knex gun i have made.

i am planning on moding it a little but i have some suggestions for you if you are going to come out with an improved version-
1.)Instead of pulling the hammer back make it so you slide the top backward and that pulls the hammer back
2.)get rid of the rod coming out of the bottem of the clip.

thank you for reading this whole post and good luck on making more guns.

this thing is not working! the front of the mag keeps on snapping off every other shot. It was also too hard to make.
