does it really act like a sub machine gun?

cazadactle (author)2011-12-12

+1 not a good replica of a real P90, should be about half the size so maybe try and slim down the mech a bit yeah?

AlphOscarAlpha (author)2011-02-05

What? The P90 is huge!

no, it's not. It's only about 50 centimeter long

If you like it so much, design it yourself as our pathetic little brains obviously cannot measure up to your obviously superior intellect.

Jedi_man (author)An Villain2011-08-06

Just plz tell me what mechanism type it is.

An Villain (author)Jedi_man2011-08-06

Are you serious?

Jedi_man (author)An Villain2011-08-07

Ugh, yes I am... I really want to know.

An Villain (author)Jedi_man2011-08-07


Jedi_man (author)An Villain2011-08-07

Grr... why won't you tell me?!

An Villain (author)Jedi_man2011-08-07


Jedi_man (author)An Villain2011-08-08

Fine, I'll ask someone else. >:(

An Villain (author)Jedi_man2011-08-08

Did you ever consider reading the Instructable do determine the action?

Jedi_man (author)An Villain2011-08-12

Yes. It dosen't say.

An Villain (author)Jedi_man2011-08-12

If the Instructable Doesn't say you can typically assume it is "standard" action.

Jedi_man (author)2011-07-31

Full auto :D ? Semi auto :) ? Ram rod >:( ?

catfacepip (author)2011-02-25

AlphOscarAlpha (author)2011-02-05

Very realistic. Sexy gun.

the-ruler-of-craziness (author)2009-01-01

have you posted it yet

No, never got the mag to work. : (

i hate it when people do that, say they make an awesome gun ,then go, i havnt posted it cos it sucks

It's true. Try and make a good box magazine that the damn belt doesn't get stuck on.

ano i beleive you but id have liked to have seen the gun

It looked a little like a real one. It had 8 simple gray connector barrels that were attached to a blender's motor, and that was encased in a round K'nex chamber that wrapped around it really tightly. Ammo fed directly into the barrels. The crank model got about 600 rpm and about 11 rps. That model shot, like, 70 something feet(I have no idea how), and got through about 14 layers of kinda-thin cardboard point-blank. That model worked like this: When you turn the crank, a series of gears rotated an 8-pronged white connector that hit "pulse" damn hard and damn quick. It was pretty cool.

yeah and i built a life size knex space ship that actually works but i didnt post it because the steering wheel didnt work

DrWeird117 (author)koal12010-03-10


Now, do you feel better?

koal1 (author)DrWeird1172010-09-29

u seem to be the one that needed to feel better seeing as u flamed for no reason

DrWeird117 (author)koal12010-09-29

For no reason? I don't know, having some smart BS shot at you for a simple advertisement seems like reason enough to me.

SonicX 22 (author)koal12010-08-09

can u sit in it without it breaking and can it move?

koal1 (author)SonicX 222010-09-29

lol im joking dude, my point was that so many people say they have an awesome gun and what not but when somebody asks questions about it or asks them to post it they say something like they took it apart already or something small didnt work

An Villain (author)DrWeird1172010-06-12


me too!!! little liars!!!!!!!!!!!

TigerNod (author)2010-04-07

Cool! 3.5

Skreetsha (author)2008-09-10

what the .... are you yapping about!? that isnt possible and if its possible you should become a real weapon designer

DrWeird117 (author)Skreetsha2008-09-10

Nah, just kidding. But now I feel sorry and I'm going to build one that uses a blender motor, as Oompa-Loompa, and apples!!!!! already know. It's almost done, but the mag jams......

Oompa-Loompa (author)DrWeird1172008-10-01

No big motor. I command thy. Use a super weak blue one or a super weak clear with red battery holder part. Then I shall make it.

DrWeird117 (author)Oompa-Loompa2008-10-11

C'mon Oompa, get out that flathead driver and put thy hands to work! On a blender! You sick freaks who got the wrong idea!

Oompa-Loompa (author)DrWeird1172008-12-08

I have no clue what you just said.

DrWeird117 (author)Oompa-Loompa2008-12-08

Late response FAIL. I meant, get out your screwdriver.

Oompa-Loompa (author)DrWeird1172008-12-08

For what?

DrWeird117 (author)Oompa-Loompa2008-12-08


I have a spare blender. The jug bit smashed.

Woo hoo! Remove the plastic case and keep the blade, but take off the actual blades, leaving only the metal pole.

Oompa-Loompa (author)DrWeird1172008-12-09

I have no blenders to take apart, and how would you mount a blender motor onto a knex gun? I though a knex "blender motor" was one of those large orange ones. Motors aren't my strong point in knex and I rarely use them.

DrWeird117 (author)Oompa-Loompa2008-12-09

No, I mean an actual blender motor.

Oompa-Loompa (author)DrWeird1172008-12-10

Well, are the big orange ones called blender motors or not?
