To get 30FPE it will take approximately 2.2 grams of CO2 per shot with the 120cc tank i will have screwed to the Sodastream bottle, so the math says 182 of usable shots. So i can safely say 150 shots per tank.

I love seeing custom builds. Following this build with interest. CO2 is well capable of 30 ft-lbs in .25 and it may use less gas than expected. e.g. I got 26 ft-lbs in .35 from a 6" barrel and it used 1.1 grams per shot. |

You could buy yourself a benchtop lathe. That'd open up another slippery slide to fall into. :)

Trigger is made from recycled beer cans. I melt them down in my big furnace into ingots. That is a leftover bit from my melt. So the trigger is made of beer!

Speaking of mods. Has anyone ever tried one of these in a co2 gun? Just wondering if it would actually work if I was to buy a co2 gun and use this instead of buying the disposable ones.
I just found this on AliExpress: | Outdoor Inflation Reusable gas Tank Tire Inflator Stainless Steel Mini Pump 8/12/16g Co2 Cartridge MTB Bicycle Bike Accessories https://a.aliexpress.com/_mtqUWl9 |
