Introduction: UP3 Knex Gun

Picture of UP3 Knex Gun


-Has all the power, reliability, etc of the UP2, but is thinner, takes less parts, has a stronger handle, and is much much simpler.
-In the areas where the UP2 was a yellow rod thick, the UP3 is only a white rod thick.
-Also uses no y-connectors or cut parts in this version.

-Can't hold as many elastics as the UP2 (but can still shoot through cardboard with unsharpened gray rods).

I'll make instructions sometime.

Kinda looks like the ray gun from CoD

TheKnexDemon (author)dommy2012-04-06

It looks more like the winters howl from CoD

TheKnexDemon (author)dommy2011-12-06

KnexFreek (author)2011-04-28

Looks awesome!!!! people need to understand thats its not all in the looks, its in how it works. And this thing has serious power. 5*

DJ Radio (author)KnexFreek2011-07-31

Yet you preceded that statement with "Looks awesome!!!". That was funny.

crazykiddo (author)KnexFreek2011-07-29

yes thank u someone also belives that the looks r nothin it the workings

Oblivitus (author)KnexFreek2011-04-28

Thanks a lot Kev. I think some people look at this and think this type of gun is obsolete.

reminds me of my modded up2

TBH my favourite ss pistol still has to be my Magnum

#note the version shown in the picture below is outclassed by the new version

Looks somewhat flimsy, and the trigger a bit short, but a gun this small can shoot through cardboard? Nice.

Oblivitus (author)prodo1232011-04-23

Thanks, but it's not flimsy. Notice that the handle is attached in 3 places.

prodo123 (author)Oblivitus2011-04-29

I attach mine in at least 6, because 3 is often not enough to hold a gun together.

DJ Radio (author)2011-04-22

The UP2 was better. The trigger was stronger. Also now the trigger block is too far forward to be considered a real performance gun. The farther back a pin is, the more momentum a pin gains when it travels.

Oblivitus (author)DJ Radio2011-04-22

It's only one connector further forward, haven't measured it, but still seems to get the same range. You're right about the trigger though, it can't hold as many elastics.

Oh, and don't lecture me on pin momentum, everybody knows about that.

DJ Radio (author)Oblivitus2011-04-22

The trigger on your UP2 seems stronger.

Oblivitus (author)DJ Radio2011-04-23

Oh, and if you really wanted to, the trigger here could be made to hold as many elastics if you glue it.

Oblivitus (author)DJ Radio2011-04-25

Lol. What?

DJ Radio (author)Oblivitus2011-04-25

Watch the video.

Oblivitus (author)DJ Radio2011-04-28

I did lol, that's why I said what.

Oblivitus (author)DJ Radio2011-04-23

I'd also like to say that the UP2 is still an option for those who want a gun with more elastics. It's not like I've deleted it by making a version 3.

Oblivitus (author)DJ Radio2011-04-23

It was. I figure that most people don't use that many elastics anyway though.

SomeAsianKid (author)2011-04-24

I have to ask how come you're not posting knex recently (besides this) and why are the guns single shot?

Oblivitus (author)SomeAsianKid2011-04-24

I'm almost 20 years old. Enough said.

TheFoofinator (author)2011-04-22

Wow, you have been away too long. It is good, but to add more power make the trigger block further back. BTW this has a contender now : DjRadio's beginner pistol It is designed for power in mind, like yours :)

DJ Radio (author)TheFoofinator2011-04-22

Unintentional competition FTW.

Oblivitus (author)DJ Radio2011-04-22


Yeah, I use word! What!? What foo?!

DJ Radio (author)Oblivitus2011-04-22

I use OpenOffice. It's free. You wasted $150 on Microsoft.

Oblivitus (author)DJ Radio2011-04-23

I use open office too. I was trying to be gangster, lol.

DJ Radio (author)Oblivitus2011-04-23

Looks like I've been reading too much successful black man.

Oblivitus (author)DJ Radio2011-04-24


Oblivitus (author)TheFoofinator2011-04-22

Range, not so much power. I'm not so sure that the range could be improved by putting the block back further than it already is, I think that there may be a limit to range because of the ammo. This gets 50 feet with yellow rods. Do you know how many feet DJ Radio's gun gets? There are other advantages to this gun too though that the standard doesn't have. It's best feature is it's 100% reliability. It's a tried and tested system that's been evolving for the past couple of years (not the UP3, but the history of versions; the UP2, UP, GP, JP, and DD-27).

Glad to know I've been missed. Thanks for the comment. :)

DJ Radio (author)Oblivitus2011-04-22

You can use any ammo with my gun (except maybe green rods but I'm not sure) so there really is no hamper on range. You could use finned red rods on my gun and get superior range compared to similar pistols. Oodammo gets superior accuracy, not so much range.

Oblivitus (author)DJ Radio2011-04-22

But yellow rods and longer will fire high with a barrel that short. I could shorten the barrel too, but I prefer the accuracy with yellow rods.

DJ Radio (author)Oblivitus2011-04-22

Barrels like that never fire high for me. Besides, finned red rods get pretty much the same accuracy and don't flop in the air.

Oh and I looked at your UP2 closer and WTF NO BULLET LOCK?

TheFoofinator (author)DJ Radio2011-04-23

I don't think it needs it, the friction of the barrel should be enough to keep a yelloe rod in.

Oblivitus (author)TheFoofinator2011-04-23

It has one. He overlooked it.

DJ Radio (author)Oblivitus2011-04-23

In my defense, it looked like a brown connector.

DJ Radio (author)TheFoofinator2011-04-23

Nope. A connector hole is wider than a rod so there really isn't too much friction.

Oblivitus (author)DJ Radio2011-04-23

There is a bullet lock. I'ts a ball socket connector, like on KILLERK's pistol. How did you miss that?

DJ Radio (author)Oblivitus2011-04-23

I took an EVEN closer look and you're right, it looked like a brown orange connector the way you took the picture combined with shading. It's really a ball socket and blue cap. Sorry.

TheFoofinator (author)Oblivitus2011-04-22

And for your information, if anyone calls it noobish, just say it's old school, because it is, old tech, but amazing performance :)

Oblivitus (author)TheFoofinator2011-04-22

All right, haha. Too true. Good and old isn't bad.

apples!!!!! (author)2011-04-24

Nice to see you're still around and posting. Also, good work!

DJ Radio (author)apples!!!!!2011-04-24

Lol this is his first knex post in 1 year 2 days.

apples!!!!! (author)DJ Radio2011-04-24

Yeah, I noticed. It's awesome seeing the people I started out with still going, even if they took a uhh...long break lol.

shadowninja31 (author)2011-04-22

I remember these guns! Great job! Are you ever going to make the Z35 better?

Oblivitus (author)shadowninja312011-04-22

Thanks. I'd try to make the Z35 better but I might blow a head gasket, lol. I don't think I could make that design function any better. I'd have to design a whole new gun (which I've tried 2 or 3 times to no avail).
