I was working to finalize and test this weapon, I think it was decent, and it shoots very well. I built a stand to store the weapon, and to use it when needed.
I just fail to install the open sight, which I am building with the greatest dedication, because the barrel is a jewel, and it is very precise.
In this weapon, you have to manually load the lead pellet from the "cup", and then press the red button on the front of the weapon for one second and it is ready to shoot. The other button, orange, smaller, is to depressurize the system if necessary, they are the only two commands it has. I installed them at the front, because it is more comfortable to operate, because it is not necessary to disassemble the firing position.
The compressed air tank in a 500 cm3 CO2 cylinder, which is filled with air up to 70 bar, and the pressure regulator that decreases to 6 bar, is a bit large but works excellent. I can regulate from zero to 15 bar with good precision. The idea is to put a strap and it goes behind me, on my back, to be able to make the weapon portable. The butane reservoir is that shiny tube of color which is a modified perfume spray.
I've tried everything and it works fine, and it gives me about 70 shots or more. I tried it by shooting out of ammo in groups of 10 and then pausing, so as not to overheat everything. More than enough to shoot 20 or 30 pellets from time to time.
The energy of the shot can pass through three cans of canning from about 8 meters. When I have the sight installed I will do tests at a greater distance, but for a weapon that I shoot at home, I agree. In the future just for testing I will raise the pressure to 7X.
The total weight is 2100 grams, and it is very comfortable to hold.
I leave some photos and when possible I will make a video to share here.
