Introduction: UKP (Universal Knex Pistol)

Picture of UKP (Universal Knex Pistol)

UKP v3

A project I've been working on "on and off" this initially started off as my Desert Eagle project back in august of last year (forum topic was removed). From time to time I would change a part here, add something there and eventually came to what you see now. Any suggestions are welcome, and don't hesitate to be critical. 

- NEW (at least I think it is) removable magazine system (more in depth below)
- Iron sights
- trigger guard

- 5 round standard clip or 3 round quick clip (a quick clip can be loaded in around 1.5 seconds)
- 20-40ft range
- relatively compact 

- last round occasionally jams
- small mag capacity

The magazine:
- the magazine uses an angled pistol handle sort of like the one seen on the TDS. This angle is slightly greater than the TDS's angle do to a different placement of rods. This increased angle allows for the acceptance of GD1 mags that lock into the handle of the pistol via small cracks in the handle.

nice gun you should post it

gordanfrohman (author)2011-04-16

It kinda looks like the fallout 3 10mm pistol.

Why do these peole say it sucks? I think its a great gun by the looks and performance! 5*

osi (author)KnexFreak3602011-03-03

Thank you!

osi (author)JDproductions2011-01-11

Thanks! and how so?

JDproductions (author)2011-01-10

yep, it looks like an usp but not under the barrel part

knex obsessed (author)2010-10-29

it looks a little bit like a USP 45. is that were the idea came from?

osi (author)knex obsessed2010-12-21

The idea behind this gun was to combine the compactness of the TDS and the removable mag/ larger round of the GD1 (which are both excellent knex guns in their own ways) it was just a bonus that it ended up looking like a USP...

RMConstruction (author)2010-07-25

Glock 18 with laser... At least, looks like one...

osi (author)RMConstruction2010-08-14

yea... It pretty much is... but I wasn't going to call it a K18... although maybe I should have...

~Aeronous~ (author)2010-07-22

Not a new magazine system. Me and Visper made a Micro Uzi with a removable mag like that. Make the trigger block behind the handle, by using a Seleziona type bullpup trigger system.

osi (author)~Aeronous~2010-07-22

Which one of your Uzi's? I want to see... I don't think it locks the same way as mine... and not at the angle my pistol has... because a micro Uzi would have a vertical handle...

~Aeronous~ (author)osi2010-07-23

Oh wait it is, sorry. I didn't notice the bullets where vertical. Buy a small spring, that way you can have an internal mag pusher.

~Aeronous~ (author)~Aeronous~2010-07-23

Also, like I said make it block behind the handle.

osi (author)~Aeronous~2010-07-23

do you have a link for it? I looked on Seleziona's profile and couldn't find it... maybe I didn't look hard enough...

~Aeronous~ (author)osi2010-07-23

Its on his PP2000. Its a bit hard to miss, but he has posted around 20 ibles, so just click back if it is not there. I could help you with it if you need any help, Selez is on holiday.

osi (author)~Aeronous~2010-07-23

hmm... do you think it would be worth the increased range to change the whole look of the gun? I mean if its only another 5 ft then it might not be worth it... plus... (this part is really bad) I don't know exactly how my gun's ammo feed system works... it just does... lol... somehow a broken orange connector rotates the round from vertical to horizontal directly behind the trigger... also the lach of the trigger mech being right there might make the round fall out... I'll take some internal pictures for you to look at (if you want) maybe you could make a suggestion...

~Aeronous~ (author)osi2010-07-24

I'll have the pics ASAP please. I think I know how it works, but it would only work with smooth ended ammo. It would not be five feet range, more like 20ft extra.

osi (author)~Aeronous~2010-07-26

I took the pictures for the Ible, I'll put them up later and then make the Ible...

~Aeronous~ (author)osi2010-07-26

Good. Notify me when it is finished.

osi (author)~Aeronous~2010-08-02

Just did the intro to the Ible... sorry its taking so long... I also determined the caliber :) .3125

~Aeronous~ (author)osi2010-08-02

Great. Estimate?

osi (author)~Aeronous~2010-08-09

scratch that... I just tried to shoot it and the gun fell apart internally... I need to modify it a bit... then I'll put the Ible back up

~Aeronous~ (author)osi2010-08-09

How long?

osi (author)~Aeronous~2010-08-12

fixed it... but now I've got to retake the pictures of the internals and edit the instructable... probably by the end of today

osi (author)~Aeronous~2010-08-09

Finished It... go take a look

osi (author)~Aeronous~2010-08-09

got the intro done... been playing ps3... gonna do some more of it now... maybe by mid august? oh wait it is mid august... probably somewhere in the 20s of august...

osi (author)~Aeronous~2010-07-28

I'm gonna take a video of it firing too... and one of the reload... I think the reload is the best part of the gun... you can fire 5 rounds from a standard mag, remove it, put in a 3 round quick clip, and fire the 3 rounds from that in about 10 seconds

osi (author)~Aeronous~2010-07-23

hmm not a bad idea... that would be epic... how would that work though? do you have a picture? or would it just be a long spring?

~Aeronous~ (author)osi2010-07-23

It would just be a long spring, all you would have to do would be to close off the bottom part of the mag.

but that would make the gun less compact

osi (author)altair ibn la ahad2010-07-23

very true... I was aiming for GD1 power with TDS size

altair ibn la ahad (author)osi2010-07-23

i built it and there was a problem with a trigger so i through it at the wall.

You couldn't have built it right. You are a noob, and I am having trouble from attempting to build from the pics.

ii have built it and it was freaking easy

You are really pXssing me off, you keep claiming you are so much better than everyone else and have nothing to prove it with. You suck.

i will post a pic of it tomorrow


am posting as a slide show

osi (author)altair ibn la ahad2010-07-23

my gun? or the GD1 or the TDS

osi (author)~Aeronous~2010-07-22

Oh and thanks for the subscription :)

TwistedParadox (author)2010-07-24

You should make the handle bigger so you can get a bigger magazine in and therefore, more ammo

osi (author)TwistedParadox2010-07-24

yea i tried that with the desert eagle project... the handle ended up being to weak and in general, uncomfortable... but I see what your getting at... maybe I could modify the mag to rotate the rounds vertically... I'll try that later... too tired right now...

~KGB~ (author)2010-07-23

looks cool

talons98 (author)2010-07-22

that hard work really paid off please post
