look at the picture

you can put as many rubberbands on the back you want. because knex gears dont have a very small gear the slowest you can slow down the firing rate is put a black gear in the place of the red gear. then you turn the red gear back until you cant not and then push the trigger and turn it the rest of the way. then let go of the red gear and load some more rubberbands and repeat. n if you load to many rubbarbands when you pull the trigger it will launch them all.

I only build guns for looks. 2.5*
dsman195276 (author)  lowe3 years ago
In honesty, I don't see the point in building K'nex guns for looks alone. Though the look is somewhat important to me, all my guys are really built for function before anything else. I'd suggest looking elsewhere if you're looking for good looking guns.

As for this gun, it was much less a real gun then a prototype for a semi-auto. The mech is all I care about on this gun. I know this gun is a frame, I didn't build it to be amazing, I built it to work lol.

Its wayyyyy too much of a frame. Either fill some of it up, or shave some of it off.

looks like a skorpion...without the mag pretty good gun id rate it a 3
Spycrab4 years ago
I built it, and so far it's a picky gun to fire. :p I kind of wish I could fire it without having to pull the trigger-as-fast-as-I-can-or-else-all-the-ammo-will-pop-off-at-once, you know? It's got a pretty neat design, though, but a weird handle that bends the parts in wrong ways, so I'll give it a 3.5*
dsman195276 (author)  Spycrab4 years ago
Haha. This was one of my earlier guns and not the best built one. I'm sure that if i wanted to I could redesign the handle and such to work better, but i'm not amazing interested in working on this again. As for pulling the trigger as fast as you can/ you shouldn't have to unless you add a bunch of rubberband(I believe around 10. I can't be certain though since i don't have the gun anymore to test that). It does sound like it's not working correctly though. When you pull the trigger back all the way the front slide part should be blocking the small gear from spinning if that makes any sense.
There's just this certain spot where, if you hold the trigger a certain way, the gear will continue to spin, and nothing will stop it, which will release all the bands. Because the bands are pulling 'hard', there are times where the gear will continue if the trigger isn't pulled fast enough. It may be my choice of bands, they may not be long enough or whatever, but I MAY try modding this later. :)

HEY!! It looks a little bit but it DOESN'T WORK!!! I have wasted my time to build it and it doesn't works.
dsman195276 (author)  hoi5 years ago
i can assure you that it works. are you loading it right? putting one rubberband on and then advancing the read gear back one shot?
hoi dsman1952764 years ago
yeah i did but it just don't work.
bboy185 years ago
this is good but pushing this together is hard :(
WOW! Thats the best RBG on this website!! (No Joke.) and yes, i have wasted my time to look and make all the other ones.
dsman195276 (author)  therandomperson5 years ago
thank you for the complement! i am still not sure that this is the best RBG out there though. it is one of the only semi-autos though(the definitely the only one with this system.). you should try down-gearing the read gear(if you know what i mean) to give the mech some more power, and so the red gear does not have to turn so much to fire(i might just build this again and show you, the mod shoud make it 10X better)
this and the RBG repeater that uses 2 gears. this is better as more force is used up firing the band than torquing the 2 gears.
yeah, thats what my slight problem was that if i put more than 16 rubber bands on, the tan clip connecting to the small gear kept on coming off, but i changed it for a red gear, now it's perfect! and ive made it into a fully automatic SMG. i will be posting pics soon

but when i pulled the trigger it still blocked the cog
jashaszun5 years ago
this gun is bad it doesnt work! the trigger doesnt do anything it just blocks the cog
DrWeird1176 years ago
Help! When I try to fire, it shoots all rubber bands loaded on. What am I doing wrong?
And I'm only putting on two!
dsman195276 (author)  DrWeird1176 years ago
ok, are you putting then one space apart? because that is your problem, you need to move it back one space(move it back when you pull the trigger) and then load it.
Ooooooooooooooooooooooooooooooohhhhhhhhh....Soory for late response but I still have it!

I think that this is a testament to the improvement of k'nex guns in the past year.
dsman195276 (author)  Oblivitus6 years ago
it was ok, i always wanted to set it up and gear it for torque, but the system was pretty flawed.

rbg=rubber band gun noob lol
lol rpg means rocket propelled grenade launcher
You build awesome guns, but you post a gun like THIS? WHY???
dsman195276 (author)  Darth Trainman6 years ago
