if you want an example of a TRUE semi auto (i've tested it myself, it's pretty good) here is a link:
https://www.instructables.com/id/Truly-semi-automatic-knex-gun/
if you haev enough rubber bands on it, it's pretty powerful
i would recommend you build it and tell me if you like it

This isn't semi it's got a ramrod that you have to pull back each time

dang i wish i could post on everybodys instructable person page " people! semi-auto guns are guns that fire multiple times without reloading or pulling back the firing pin".

This is not a true semi auto gun most people believe that a semi auto gun is a gun that loads the bullet automatically when you pull the pin back but this is not true. A semi automatic gun loads the bullet (or pulls back the firing pin) when the trigger is released which makes it so all you need to do to fire is pull and release the trigger.

its not semi- auto, its a block trigger. and the gun has to shoot by pulling the trigger and it has to shoot without releasing the trigger. If you have to release the trigger to shoot, its really a repeater.

dude, stop with the block trigger comments!

author
DJ Radio (author)ILIKEPIE3332009-01-19

Well, im just pointing out that this gun has a block trigger, what is wrong with that?

author
ILIKEPIE333 (author)DJ Radio2009-01-20

I guess its just that its very annoying to me when people post comments putting down block triggers block triggers was the first trigger on a knex gun and that it should be shown respect plus its not someone's fault if they cant come up with anything better, because if it works, use it block triggers should not be insulted because of what they are

 Block trigger racism but Dj is right Block triggers are really cheap you just need some creativity....

author
jj65456 (author)ILIKEPIE3332009-11-06

you ever thought some people might like a real trigger to allow them the feel of a real gun

author
ILIKEPIE333 (author)jj654562009-11-06

I know, everyone is entitled to their own opinions
I myself like true triggers and think they are superior, but there are good things about block triggers and they were the "founding fathers" of knex guns

DJ Radio (author)ILIKEPIE3332009-01-20

I wasnt saying anything against block triggers, i just said it was a block trigger.

author
ILIKEPIE333 (author)DJ Radio2009-01-21

ok, but keep that in mind

author
noobererer (author)ILIKEPIE3332009-06-07

yeh i know most of guns that i randomly make have block triggers or i just use some1 elses true trigger :P

author
ILIKEPIE333 (author)noobererer2009-06-07

thank you for agreeing

ptg76 (author)ILIKEPIE3332009-04-11

he is right stop

But one that will be cool is a truly semi auto block trigger.

author
DJ Radio (author)Millawi Legend2009-08-08

That is impossible, since it has to be a true trigger in order to cock the gun and shoot it in one trigger pull.

mister97 (author)2009-07-24

ugh ive been trying to find a simple semi-auto knex gun but nobody knows what semi auto is... does anybody know where instructions for a truley semi auto knex gun that doesnt use too many pieces?

author
Millawi Legend (author)mister972009-08-08

I have 2.

author

and 1 full auto.

author
Merugop (author)Millawi Legend2010-05-13

 I believe it's fullauto but then it's just a gatling or motorized one that shoot like 2 0feet...........

Go to ExtremeBuilder's semi-auto. Sorry for the late comment, though.

minime12358 (author)2009-06-21

Sorry if this is slight spam, But would anybody be annoyed if I made a Truely Semi Automatic Gun that is block trigger? I have not built this at all but I have some ideas for it.

author
ILIKEPIE333 (author)minime123582009-08-03

it would be fine if you did, but better if you didnt
(I hope you know what semi auto truly means)

author
Bartboy (author)minime123582009-07-04

It would annoy some, but it's still worth doing. The thing is, that sounds impossible....

author
TwistedParadox (author)2009-04-18

'tis not semi-auto, looks good though

author
DJ Radio (author)2009-04-12

I wasnt complaining, im just saying it has a block. BTW, that was pretty late?

author
ILIKEPIE333 (author)DJ Radio2009-04-12

I just wanted to say something, I was bored

author
feralin (author)2009-03-14

I think it's a preeeeeeeeeeetty ok gun, 3.5 Star

author
ILIKEPIE333 (author)2009-01-11

you posted a block trigger so you are therefore saying you hate your own gun

author
ILIKEPIE333 (author)2009-01-11

DJR! We get it! It's a block trigger. Why are you so Anti-Block? I know they are out of date but they're not the work of the Devil so Cheesus Christ stop replying to each comment.

author
DJ Radio (author)TheDunkis2009-01-08

im not against blocks, I think he just used the semi-auto thing to cover the trigger up.

author
DJ Radio (author)2009-01-07

not a semi auto. you have to pull a ram back. and the gun itself is ok. 3* for mislabeling and not having an intro with the full gun.

author
The Jamalam (author)2009-01-06

tape on the gun! and also get a proper picture of the gun on the 1st step. its not semi auto its pin action

author
juneapaluna (author)The Jamalam2009-01-06

Is tape really that big of a deal? but I do you what you mean about the intro and how it's not semi :(
