SAWED-OFF RIOT GUN redone!!!

[Urban Ninja]

Think thats bad? Move to aus. In sydney they are trying to ban cap guns! No bb guns or anything like that. Its sooooo strict.

[Brian the brain]

Cap guns resemble real guns and are outlawed where I live...
Belgium sell em and that's like an hour drive.
(3 hours to Germany)

That is awesome. I would also like to see a video of anything that thing will do. Parts list would be awesome too.

[Brian the brain]

I don't have much time on my hands and I'm currently in the process of building a CO2 powered strafer.So video will have to wait.
And about the parts list...I modified some of the compression fittings to fit into one another.I doubt this gun can be copied off of a parts list.
But let's give it a try

The chamber is 28mm steel with compression endcap.The fitting connecting the chamber to the action part of the gun is a filed down 22mm T that is compressed into the "top"28 mm T.
The barrel is connected through a 22/28 reducer, also filed down to fit into the 28 mm T.The part where a 22 mm pipe used to connect was inserted into that 28 T and a small piece of 22 mm pipe was hammered into the reducer kept in place by a piece of inner tube bike tire.This also makes the connection airtight. Ballvalve is a standard ballvalve with some kind of emergency tap on it.I took out that tap and fitted my shrader in it.THe opposite hole (wich was sealed with a plug when I bought the valve) just happened to fit my gauge.The valve's original handle was filed and bent to form a trigger.

Handle (grip) is a piece of bent pipe from an abroller device.(27 mm or so)Made to fit the compression fitting with the help of some inner bike tube cut into a ring
Piston is made from bike inner tube rubber,26 mm pipe, bolt, nuts and washers
A spring pushes the piston onto the "hammered" piece of 22 mm pipe.Other side of spring rests on the ball inside the ballvalve.(doesn't jam or any thing since the ballvalve never opens fully)

There are some more parts like a reducer connecting the chamber to the 22mm T and an endcap on the other side.Ofcourse some smell sections of pipe onto wich the fittings go.Only two fittings don't use a pipe between them( the adapted ones) to save space and get the gun looking more compact and to loose dead space between the piston and the barrel.

Hope this helps.

My mum comes from Holland!and any idea on the veloceity of the marbles?and i this topic is a few months old but i would like to no the muzzle velocity and weather it is going supersonic

[Brian the brain]

I haven't got the slightest idea on the velocity.I'm sure it's not supersonic.
No sonic boom.I don't have any open space to try a long distance shot so it's kinda hard to guess the speed.It seems to be faster than my SKIFF A 3000 CO2 pistol from anics.

[Brian the brain]

Sorry about he double post on my own subject but this gets noticed without me having to open a new thread.

My question...what do you guys think?
Should I keep the gun this way or as I'm now wondering, should I add a CO2 bottle to pressurise it fast and repeatedly, and add a loading system.I have the parts, but I'm hesatating.I like the look of the gun as it is...

Any comments??

MMMMMMM sawn-offs,the gun looks real nice and i think you should leave it.

[Brian the brain]

I'm afraid I did change it somewhat anyway...Just read the (orange) update

[)DEMON(]

I love this gun!!, by any chance could you draw up a diagram becuase I am still having trouble understanding this (my knowlage of metal fittings is not good). Could you also post some pics of the piston and other parts? I have trouble with pistons(AAAAA!!) and I just want to know how they have to be to make them work. Yours seems to be a good example and is one of my top favourites.

I live in friggen communist new jersey! There's a law for every fukin thing you could think of. It's only luck that's stopped me from getting in trouble so far.

Just yesterday I was at home depot buying pipes and I was explaining how my new gun will work and a cop was standing right next to me on his cell phone. I almost shit.

[beebs111]

most cops dont care about spudguns, the cops that live near me are pretty cool

[huse_spud]

this gun is really fancy. it's one of the more threatening cannons on this forum.

ive yet to make something really spectacular but it seems like there's no time to do this stuff.

[)DEMON(]

Really? how come? Most of my spare time is put towards building spudguns. My piston valve is coming along nicely, it is pressuse rated to a few hundred psi. It is made with galvinized steel, copper pipes and brass fittings. I would still like to see pictures of the inside of this gun and some pics of your co2 set-up. I have got a better chance of George W hitting on my mom than the police caring about what I build.

[Brian the brain]

I just went to grab my camera and it turns out my wife took it to take some pictures of my son while they're on the beach. ..Damn! I put it on the table last night.Wanted to wait for better lighting.Women,...you can't live with them!

Most threatening cannon ay? That was my no.1 criterium! Hahaha

I built it with a possible burglar entering my house in mind.

I mean...I would only scare him with the sound and looks...ofcourse...
