Introduction: K'nex Pseudo Semi Auto Pistol V2

Picture of K'nex Pseudo Semi Auto Pistol V2

This is the version 2 of my pseudo semi auto pistol. First, I added grey rod firing pins instead of red rods to increase power.
I also made a slight modification to the trigger mechanism. I also made the gun longer to accomadate the longer firing pins.

Sigh, double barrel, not semi-auto.

This is not just a double barrel gun. I forget to put the part in the instructable
about that it uses a alternating trigger mechanism. When you pull the trigger
once, it fires one barrel. When you pull the trigger again, it fires the other barrel.
If you still do not understand, then ask Oblivitus about the alternating trigger
mechanism, because he came up with the idea.

Ok, but this still isn't semi-automatic. I can ee what you're saying though. For the record, lets just call it a double-barrel-semi-automatic hybrid mech.

Isn't that what pseudo semi auto means?

essentially yes, but not necessarily a double barrel (usually it's more).

~KnexBuild~ (author)Sharir17012012-07-16

Yeah, but I wanted to keep it a compact and small pistol.

i agree with the chunky sniper. call it whatever you want. pseudo semi auto, double barrel semi auto, alternating semi auto. whatever. this isn't innovative or new. it has been done before, and it isn't a semi-auto. it's an alternating repeater. the reason why it isn't a semi-auto is that it has a different trigger each time. i know, oblivitus' Z3 and SA 3252 have it, but they're still innovative and brand new. i have told oblivitus, when i was working with him, that i think he should make a 1 trigger mech on his SA 3252. i know how to do it too, but he says he doesn't have much time to work on it now that school has started again.

What do you mean by "a 1 trigger mech" ? The Z3 is extremely large, so it is going to be REALLY hard to maneuver around in a war with it. Oblivitus said
that it is 9 pounds. If this isn't semi auto, than no K'nex "semi auto" is. The only
real K'nex semi auto would be something like the KLS-v2 or the W.A.S.P.

i'm sorry. back when i made that comment i was a bit angry with my folks, and that tends to show on my comments. what you said is true, that this is a semi auto, for knex, but there is no true (pin) semi auto. it's a nice design, though i would have made 4 pins, as well as a magazine. also, maybe some way to cock both rams simultaneously.

If this is a semi auto, what pushes the ram rod back for another shot? Great gun though and PLZ POST ASAP!!

Thanks! =D It uses an alternating trigger mechanism. When you pull the trigger once, it fires one of the firing pins, and when you pull the trigger again, it fires the other pin. You get two shots of semi auto. I might post it today.

Nice gun! Do you maybe have an video of it in action? I'd like to see that (not needed) Also, how far does it shoot?

Do you have to have a youtube account to post videos? I haven't tested how far it shoots. Once I test it, I will tell you what the range is.

Ok, yes i have an youtube account

No, I meant does a person need a youtube account to put videos on Instructables? Today I tested the gun, and it shot about fifty feet with two
64 rubberbands.

No (I think) I included an video in my bolt-action slideshow. Play a bit around with the slideshow and you'll find the option

I looked and it said that you have to get an embed code from youtube
