Introduction: Ultra Pistol 2

Picture of Ultra Pistol 2

The best knex pistol, period.

The Ultra Pistol 2 is easier to use, stronger, more reliable, faster firing, has better sights, is equally powerful, ranged, and accurate, and accepts more types of ammo than the original.

It can fire blue, yellow, red, and gray rods (yellow fires the best).

-DSman's DD-27 Assault Rifle
-Jollex's DD-27 Pistol
-KILLERK's Pistol

NOTICE: The handle is right handed. If you are left handed, build it flipped.

As you said Oblivitus, The best knex pistol. Period.

Oblivitus (author)Inventor X2011-07-10

Thank you.

Perk1ns (author)2010-08-13

If you're using that metallic blue connector to keep the firing pin inside the barrel, wouldn't you need to weaken it, so that the firing pin can still slide easily?

Perk1ns (author)Perk1ns2010-08-13

Finished it. Indeed the best k'nex pistol. 5 stars.

Oblivitus (author)Perk1ns2010-08-14

Thank you. :)

Oblivitus (author)ol9879862010-04-05

Thanks a ton.

instruct39 (author)2010-12-24

what kind and how many bands did you use?

the knexman (author)2010-09-21

are the ball point sockets male or female?

johnguackmbl (author)2010-08-15

Do you need the ball socket in pic 7-8?

bigt4616 (author)2010-08-12

i just figured out the most amazing thing. this gun has great power and distance already... but... take two of those long balloons that you used to blow up with that little pump when you were a little kid, you know, the ones that clowns make animals out of. snip off both sides, tie each side to the other balloon. and tadah. you got a super rubberband. this came purly out of nessessity... and it shot into the woods in my back yard with an odammo yellow rod. i just looked at amazement. my yard is at least a good 80 feet long. i had to do a second one just to make sure i wasnt dreaming XD.

bigt4616 (author)bigt46162010-08-12

okay, maybe a bit too strong, just split a red rod in half that i was using as a pullback O_O

sukinmaru (author)2010-07-28

Ok... I finished at 1:32am central time... I think... I think Imma go to bed now....

sukinmaru (author)sukinmaru2010-07-28

I deleted my own comment because it was redundant. This doesn't work with #64 elastics! What elastics should I use?!?

Dr.Squirrel (author)2010-06-26

I built this for the third time, and a added a fore grip to it. Now it shoots way more percisly.

H1T4TCH1 (author)2010-04-09

 do u have 2 sharpen it?

Oblivitus (author)H1T4TCH12010-04-10

I think so.

bugjojo (author)Oblivitus2010-06-23

You dont need too. Just rem0ve that piece at the front-inside of the barrrel at first but then only shoot parralel. Put it in if your gun works,

H1T4TCH1 (author)bugjojo2010-06-23

ah thanks man

H1T4TCH1 (author)Oblivitus2010-04-10

 yeah i wanna be sure cuz i dont wanna sharpen or break knex pieces...

H1T4TCH1 (author)H1T4TCH12010-04-10

 i know its a great pistol but i only have one black rod and sharpen it would be... yeah you know... not good.

bugjojo (author)2010-06-23

Note on step 2 of this you need to remove the green pieces

Oblivitus (author)bugjojo2010-06-23

What green pieces?

uberrobodude (author)2010-04-30

Which is better This or your beast pistol?

Oblivitus (author)uberrobodude2010-05-01

The UP2.

uberrobodude (author)2010-04-20

Is there any way to save two black hinge pieces, I'm a noob, and no good at modding.

Actually their green but you know what I mean

I only need one

Scratch that , I need two. Srry.

Please help!

Never mind, I dont need any. srry.

 Actually, if you still need help, I have an alternate trigger assembly (no hinge peices) posted on the Beast Pistol instructable. The Beast Pistol assembly is mostly the same as the Ultra pistol one, and is easily adaptable.

uberrobodude (author)2010-04-20

On pic 7 what is the blue thing above the ball socket? is it a metallic blue end piece?

I hope it is cuz i already built it.

Merugop (author)2009-12-25

 can i replace the metallic blue tan with summthing else?

Oblivitus (author)Merugop2009-12-25

Not likely.

ol987986 (author)Oblivitus2010-04-05

Oblivitus (author)ol9879862010-04-05

rrr67 (author)2010-01-23

ol987986 (author)rrr672010-04-05

sorry for l8 reply but yes they can be white, grey iis the retro version of the piece.

MegaMetal8 (author)2010-02-27

looks a bit complicated

does it have a mag?

Oblivitus (author)MegaMetal82010-02-28

No, it's a single capacity muzzle loader. Watch the video on YouTube;

MegaMetal8 (author)Oblivitus2010-03-01

iv watched the vid
Have u seen my new mini pistol with trigger

im really suprised coz a load ov good knexers hav commented and 5*!!!

a jar of dirt (author)2010-02-26

yes actually, a piece that looks just like it, but with an appendage like a rod sticking out,  it should have been in your knex set.

KNEXFRANTIC (author)2010-01-31

its awsome

Oblivitus (author)KNEXFRANTIC2010-01-31


KNEXFRANTIC (author)Oblivitus2010-01-31

Oblivitus (author)KNEXFRANTIC2010-01-31

I saw it, it's good. Try to make a more realistic trigger.
