Picture of semi automatic knex pistol
this is it! the first ever true trigger semi automatic bottom loading magazine pistol.i was playing around with different mechanisims of how to make a semi auto like having the trigger pull back the ram but this did not work so i moved on to a multiple rubberband system and how a rbg could be adapted and this is what i found...

ever noticed how all the good guns seem to not have the pictures just to annoy us?
Copy and paste the picture into some picture editting program to see it.

I built it, it was kind of inaccurate, slow reload, but the handle (when changed around a tiny bit) was SO FREAKING COMFY :D I'm going to have to change it around to just be an rbg and use it for the kick-butt handle. Overall...4* :)
awesome gun i love it 5 stars
it takes way to long to reload you need to make that better

I modded this a bit, so its like a table-top cannon. When you press down on the top, it fires and then it springs back up again. Semi auto of course. If I post it, I'll give you 77% credit.

ok, post away!
It is up, but only as a slideshow as my brother dis-mantled it.
why did he take it apart?
He was probably a jerk.
WTF if u post a knex gun people expect it to shoot knexs
srry thought it was rbg cant see why though...used to be a noob...
bedbugg2 (author)  PieMaster7777 years ago
what? lol...
he probely is a NOOB that did not look through the instructable and just thought it was a RBG.

i've experimented with having a full auto knex using the rbg style mechanism but the rubber bands all shoot before the bullets can be reloaded by the magazine. How do i slow the mechanism down that releases the rubberbands?
bedbugg2 (author)  aikduck6 years ago
Yeah, i came into the same problem when i tried to make mine fully automatic...the only solution i could think of would to be to use some kind of geared mechanism to slow down the rubber bands.
I made something similar...

BUT!!!! before you say it is better, this one is made first so it is better. Very good work. 4.5 stars!!!
bedbugg2 (author)  Miles Tails Prower6 years ago
Wow! that really is something...much better than my design, you should post it.
You have to post that gun. It is amazing!
Thank you!!! But I'm VERY lazy, I mostly don't post instructions...
Wait, I did notice that you do post videos of instructions, so would you be willing to do that? I you just do want to, thats fine. It doesn't make a difference to me!
Yup, I'll try my best for you.
Awwwwwww... Darn! =)
actually, ive done my take-on of your gun. ill post pics soon

Thanks bedbugg2, the gun shoots well
DTass6 years ago
I have the gun built, but I don't understand where to put the green bullets.
bedbugg2 (author)  DTass6 years ago
you put them in the magazine, picture 3 on the last step, the part wite lots of white snowflakes. you take the rod out which is held in by the elastic band, drop them in one by one, once you have loaded all 8 you put the rod back in to press them against the sight. just message me agian if you have any more problems :)
can i use the trigger system for my gun? (cridet to you)
bedbugg2 (author)  knexsuperbuilderfreak6 years ago
sure, post a link when you're done.
how bout me? i have an excelent mech (in my opinion) and i was looking for something so it can shoot rods to (i was to lazy to look at the dunkis's mech and follow it). if u wanna see i have a link to the forums here so can i please base my rod shooting mech off of urs? i will give u credit in any way u want me to. i feel like a complete idiot begging u for this...
ok thanks

its a rubber band gun, aint it
Dont you get it??? the bullets are fired with the rgb system. the rubberband push against the bullet and fires it. with the rbg wheel, you can add more rubber bands than one, so its semi auto.
