sniper marble gun [updated]

[sniper hero]

hi
this is the latest gun I made
I still need to buy a pressure hose but that won't be a problem
I did some test shots and it shoots very good
A scope is mounted for sure 8)

ok now some specs :
16 mm ID barrel length one meter
28mm OD chamber 330mm long
valve: qev
pilot valve: modefied kind of blowgun
fill: bike tire valve

some shots with batteries
please tell me what you think and ideas for improving

Damage pics? Video clip maybe??? What pressure are you operating at? Are we there yet?

[sniper hero]

pressure is about 12 bar
damage pics will com soon 8)

Did you solder the end cap and other patrs to the pipe, icant tell from the pictures?

[sniper hero]

the whole chamber is soldered toghether

nice... I like the barrel.... what is it made of ?? it seems it's threaded but is it smooth inside ?

[psycix]

Mooi
Zoiets heb ik nu ook liggen, zelfde QEV en loop, maar dan op meer dan dubbel zoveel druk xD
Toevallig ook van brian the brain wat onderdelen gekocht?

How are you connecting the blowgun? Beware of extra pilot volume when adding hose.

@POLAND_SPUD
Its an aluminum barrel. They are perfect for marbles. The fit is so tight that some 16mm marbles do not fit in and others do.

[POLAND_SPUD]

where did you get it?? man... I've been looking for an aluminum pipe everywhere

[Brian the brain]

Glad to see it worked out!

My suggestion would be to get a smaller T in the back to keep the pilot volume to a minimum.


I would flip the chamber to the front and build a wooden shoulderstock for it.

I believe I've seen that QEv and barrel before

[sniper hero]

I will use a pressure hose and don't care about the pilot volume since power is more then enough for me
when a scope is mounted it's most for accuracy and ergonomics
a wooden stock:P
I was thinking of that , I might make one

[LCTChamp]

Wow I cant believe no one has blown up on him for calling it a sniper yet. Personally I don't care but it seems to be a very common argument. Well any way nice gun. It is very clean. I can't wait for some damage pictures.

nice layout;)

I like it. The more guns i see along these lines the more i want to make one. It would give my pancake compressor something to to besides fill tires.

[sputnick]

Stock and scope, then you have a sweet gun, even if the stock is pipe, its overdone, but it works.

It looks like a nice piece of work, and I really look forward to seeing it all dressed up and nice.

i like the clean look of your gun. i think i'm going to build one for next build.

however i have a question - the blow valve i've been using is rated @ 90psi with the common modified sprinkler valve for trigger setup.

what are the parts for your awesome trigger setup? and what psi are you filling the chamber up too?

i have lots of copper piping sitting around that i could use to make this.
