This is my new ghetto 6mm sniper!

It´s not finished yet but it works :lol: I just wanted to show it and ask what you think about it and what I should change etc.

I´m going to add a paintjob and of cource a scope + something where the scope is mounted on and the breech system is hidden better.

AND YES the idea did come from devilmans Combustion Sniper! I love his gun and wanted to do somthing the same.

The chamber. I made it out of two reducers and other stuff. I put the ignitor on like that to try it. (certainly not going to stay like this!)

This is the breech system. made of a copper-pipe and the tip of a soada gas cartridge.

Yes certainly ghetto... :roll: actually a little frankensteinish...

Concerning your "bolt-reload-thing"...I assume that's an attempt at a breech load system and you're still working on the bolt mech...it looks like you're going to have some serious flow restriction with that copper tip...

You should do some thing else with the masking tape barrel mount. You'll find your barrel being the projectile!!

I know it is frankensteinish. I´ll have to paint it :lol:

Oh yeah sry thats what I meant breech. :? My english isn´t perfect :lol:

I´m going to use clamps to fix the barrel. Actually the breech system works pretty good. The Gun is sealed properly and the only way out for the pressure is out the barrel.

Those weird reducers certainly make for some interesting construction. I like how they make a nicer looking stock than concentric ones.

The only things I could see changing (besides the much needed paint job and what starman said) are the shape of the forestock and the screws in the chamber. Sand it down a bit so it looks more curvy and less bulky. As for the screws, I use metal screws in my cannons, due to the threads going all the way up the shaft and the head having a flat underside allowing it to sit flush against whatever it is fastened to.

I don't think i even need to say anything.

Looks....umm, unique?
But i think starman is right. Your going to have better performance without that copper piece. If your "breech" wont work without it, at least consider making it shorter.
[Techie] 12:04 am: heck why dont i just light a fire under random cars
[Techie] 12:04 am: that aughta be fun while it lasts
[mark.f] 12:06 am: Just give us the ignition coils before you do.
