Introduction: MM-PASS

Picture of MM-PASS

Hello everyone,
Sorry for not posting anything lately, I have been building a long time on this gun.
This is what I like to call the MM-PASS which stands for:
Mr. Muggle's-Pump Action Single Shot.

I wanted to make a pump action single shot so that I could increase the amount of bands that I can pull back. I feel like the pump action feature also slightly increases the fire rate because you can keep your hand on the pump while you can't keep your hand on the firing pin of a regular gun. So that's why I made an ammo storage on the front, I focused on quick reload simple but sturdy design and power/range. This gun also has the chamber principle like the Untangle, which enables you to put more bands on the gun.
Credit to mepain for inspiration and a bit for the pump design, I didn't copy anything.

PS: If I'll ever post an instructable of this, I will improve the handle and the stock because as I said I wanted to keep the design simple and focus on the gun itself.

PPS: The gun looks a bit bend in the picture... I don't know why because it really isn't in real life....

Tell me what you think.

I made a mag fed pump-action, which can pump like five 64 bands. Might post soon. Maybe you could try to integrate the mag into the barrel?

Mr. Muggle (author)~Aeronous~2010-06-05

If I would build a mag function I'd built a turret, except I wanted a single shot not a mag fed

~Aeronous~ (author)Mr. Muggle2010-06-05

Why have a singleshot when you can have a mag?

Mr. Muggle (author)~Aeronous~2010-06-05

more range, no need to change mag

~Aeronous~ (author)Mr. Muggle2010-06-05

So its basically a pump action sniper? Maybe try and incorporate the NAR mech into this.

Mr. Muggle (author)~Aeronous~2010-06-06

where can I find the NAR?

~Aeronous~ (author)Mr. Muggle2010-06-06

You are joking right? The NAR is the most famous knex sniper. 450ft range, no exaggerating. Its on KI, its also known as the Untangle. NAR stands for Not A Rectangle.

TheChemiker (author)~Aeronous~2010-06-06

The sr-v2 is the most famous sniper. The NAR is the best and most famous single shot.

~Aeronous~ (author)TheChemiker2010-06-07

I dislike the SR-V2. The NAR is way better, gets way better range. Its the preffered sniper by anyone, because it doesn't use that many pieces. I liked RC-120-SEV way better then you. You seem to be acting like a cocky knowitall. People change with their name.

An Villain (author)~Aeronous~2011-08-29

You would know "Visper123"

~Aeronous~ (author)An Villain2011-09-09

What are you talking about?

An Villain (author)~Aeronous~2011-09-10

You used to be Visper123 however I believe you replaced him and deleted all of the Instructables featuring his name except the Visper's preview and the VPAG.

~Aeronous~ (author)An Villain2011-09-18

Also that is wrong I checked it. Almost all of his/mine instructables and previews and stuff are still there.

An Villain (author)~Aeronous~2011-09-18


~Aeronous~ (author)An Villain2011-09-23

Actually I believe ALL.

An Villain (author)~Aeronous~2011-09-24

At one point the Visper was an actual Instructable.

~Aeronous~ (author)An Villain2011-09-17

And who cared about them? What is it to you?

TheChemiker (author)~Aeronous~2010-06-07

Not really. I am not a cocky knowitall. I did not change. I think more people know about the sr-v2 than the NAR, and the sr-v2 is always refered to as a sniper, and the NAR is usually considered a single-shot, not a sniper. I don't think a NAR could shoot 450 ft angled, but that is my opinion.

~Aeronous~ (author)TheChemiker2010-06-07

Dude, build it. It gets 450ft. SR-V2 is a sniper, but its not the best. It only gets 70 feet.

TheChemiker (author)~Aeronous~2010-06-08

Any slingshot sniper gets better than 70 ft.

~Aeronous~ (author)TheChemiker2010-06-09

The 3 guns I have ever gotten to shoot past 70ft, are the NAR, the MeZak, and my own slingshot sniper which got like 72.

TheChemiker (author)~Aeronous~2010-06-07

I knew about the sr-v2 way before the NAR. I am trying not to be totally dj like, I just don't want to be the person who loves everything either. I am not trying to be a knowitall.

~Aeronous~ (author)TheChemiker2010-06-07

DJ like? Just bring me back some evidence showing that the SR-V2 gets further range then the NAR, or quit correcting people when they are already correct.

TheChemiker (author)~Aeronous~2010-06-08

Lowney's video of 500 ft.

~Aeronous~ (author)TheChemiker2010-06-09

The video is fake. He confessed. It only gets around 70ft. And besides, Its pretty obvious its fake, because otherwise how would he have known the direct spot it would have landed? He put it there, then shot it into the hedge.

Mr. Muggle (author)~Aeronous~2010-06-06

it already has that, read the description

~Aeronous~ (author)Mr. Muggle2010-06-07

Oh yeah forgot about that. All I can say now is Po$T!

I've been going through instructables, and all the best guns don't have instructions. When I used to come here more often, every gun had instructions. Why the sudden decrease in actual instructables, and the increase in slideshows?

Mr. Muggle (author)arrow shot2010-06-15

because people are often very critical on guns that aren't an improvement on the already existing weapons, that's why I posted this slideshow, to ask what people think of it first

DJ Radio (author)2010-06-03

What's the point of having a pump action single shot when turrets shoot rounds as if they were single shot anyways?  It looks like a ruined knexsayer.

Mr. Muggle (author)DJ Radio2010-06-04

This gun has the same chamber mechanism as the Untangle which makes the range better because you can put more bands on it. But this gun doesn't necessarily have to be used for war. It isn't made for looks

DJ Radio (author)Mr. Muggle2010-06-04

This gun can only be as strong as the pump is. So you can't put as many bands on as on the NAR, because the pump would break at a certain point. I know, but I wasn't referring to just the looks of the gun when I said that.

Mr. Muggle (author)DJ Radio2010-06-06

the pump won't break, if there's anything that would break it would be the ram or the trigger but the NAR has that problem as well

Mr. Muggle (author)DJ Radio2010-06-04

where can I find the NAR?

DJ Radio (author)Mr. Muggle2010-06-04


Mr. Muggle (author)DJ Radio2010-06-05

yeah, I searched, couldn't find it, could you give me a link?

DJ Radio (author)Mr. Muggle2010-06-05

Go on the chat and ask someone there for a link.

TheChemiker (author)DJ Radio2010-06-06

People on KI chat usually don't like to cooperate with requests like that. They just laugh at you.

~KGB~ (author)2010-06-03

nice gun! a mag would be better tho...

Mr. Muggle (author)~KGB~2010-06-04

MegaMetal8 (author)2010-06-03

So  do you pump it  then snap a rod out the holder and slide it in?

Mr. Muggle (author)MegaMetal82010-06-04


MegaMetal8 (author)Mr. Muggle2010-06-04

Ok thanks
