Truly semi automatic knex gun

Truly semi automatic knex gun
This gun is based off of KNEmovies design, but not his mechansim. the mechansim may be similar to his, but mine is not that complicated. My gun is not that powerful, as it only shoots 5-10 ft. I hope you enjoy my semi - auto gun.

This gun is not that great i used my best rubber bands (usaully increses the range about 20 feet) but it does not work very well not even 8 feet of range.

Oct 22, 2011. 8:08 PMSnosageman99 says:
Do you need the orange thing with the pins? Is there anything else i could use
Sep 11, 2010. 2:00 PMgeoff-2009 says:
this gun is a nice design but it lacks in power so i upgraded i to i stronger fire pin and elongated the barrel now it shoots 50 ft for instructions write a comment
Oct 9, 2011. 8:34 AMwabawaba says:
I really doubt that
Oct 3, 2010. 2:26 PMknexinglemon says:

I pulled the trigger... boom. I woke up in the hospital. It blew up in my face!!!!!!! U owe me 2 hours of my life back, and my knex shotgun.
Jul 7, 2011. 6:13 AMDB2016 says:
Yeah, usually this happens (the second part) I know whatcha mean. Not this gun, but others.
Jun 16, 2011. 6:07 PMsuperbestknex says:
hey are you serious you woke up in the hospital
Jun 14, 2011. 7:29 PMSketch98 says:
A factor that makes this gun lose power is the make shift hinge connecting the hammer to the ram. If you used a real hinge it would stop the loss to power.

This is so cool!!!
May 14, 2011. 2:11 PMMikestr12 says:
The faster the trigger move the more power it has +more mass on the pin and top it of with small ammo. Mass x Acceleration = Force. Being a geek is awsome

I have been searching for something like this for years !! this is a very good idea !! Respect 5*
Jun 23, 2010. 12:07 PMinstruct39 says:
dude you are the first person ive seen that actually built a TRUE semi-auto knex gun. Some people think they have but they havent. i have seen your mechanism in a revolver cap gun before, and is that where you got it? Anyways truely great gun even thogh the range isnt the best. 5*
Apr 14, 2010. 3:51 PM64runners says:
One problem, when I pull the trigger, nothing shoots. Instead, the bullet gets stuck in the magazine.
Apr 13, 2010. 4:01 PM64runners says:
By the way, Can you please give me a part list of this gun? I need it when I'm building so I can organize the parts. (Helps me build faster)
Apr 13, 2010. 1:56 PM64runners says:
This is epic!
Feb 18, 2010. 7:54 AMjopperdepop says:
 I built it, I really like the firing mech, but the only downside is that it doesn't shoot far:(
good gun though
Dec 16, 2009. 9:49 PMRaikou-san says:
What does the "pusher" do exactly? Is it needed for the mech to work?
Oct 6, 2009. 4:29 PMjames4 says:
