Homemade C02 airsoft gun concept

Unread postAuthor: The_Kangsta » Wed Feb 27, 2008 11:05 am

I was planning to build an airsoft sniper rifle, powered by co2. The stock is made out of 1 inch pvc, with a co2 adapter like this one http://www.bikemania.biz/CO2_Cartridge_ ... o2-reg.htm
The blow gun connecting to the 1 inch end cap leads to a system that is similar to JSR's blow forward breech here http://www.spudfiles.com/forums/6mm-sem ... 10075.html
, which then can shoot bbs from the magazine. I know that it is possible to shoot semi auto in this design, but I question the reliability and ability to shoot many bbs without having to reload the co2 cartridges, because of the small air supply. The diagram is what I plan to use as my design.

the stock is actually the chamber. the barell is 6mm and 1 yard long
If you can, tell me approximately how much power or fps I would be getting and/or how effective a co2 cartridge is

How about some more details, such as a barrel, chamber, and valve? It looks like a pistol with a stock.

And you may want to watch the language there

Looks super-duper-minycooper special. sure it'l work. Its just a pneumatic with a blow forward breach. I would recommend a high volume chamber under the barrel for compactness's sake.

So even with the tiny 1 inch chamber you are saying the co2 cartridge be effective for many shots?

And yea thanks for the idea for the chamber under the barrel i think i will incorporate that

It would make more sense to hook up one of this style of inflator to the blow-forward breech:

The trigger is done for you and you don't need a chamber.
