this is my new semi auto bb gun called the serpent it fires 6 mm bb at a pressure of 7 -20 bar with high accuracy at short to medium range it still needs its magazine to make it a real semi auto.

That's pretty beautiful, but I'm sure you could use a slightly bigger chamber. I know you're trying to keep it small though.
I think your pilot volume could be smaller and the ball valve pilot could be swapped for something a bit easier to use to keep your gun more accurate.

very nice! I like the idea of accuracy over power, but i think you ammo may hold it back. Whats the best shot grouping you have done so far?

thx i have tried to make the pilot volume smaller but i dont have the parts and i had a bigger tank but it firers harder with the smaller one and the ball valve is pretty easy to open

Great first QEV gun, looks great, and I'll bet it could look amazing on a wooden gunstock and a real trigger. Also, you share you icon with a veteran member, you migh want i consider changing it to avoid confusion

I love lamp

Can we see the rifling?
That scope could be doing more harm than good at just 10m... How did you mount it onto the barrel?
“The combined synergy of a man and rifle is matchless.
The steadiness of hand, the acuity of vision and finally
the art of knowing how to make the rifle an extension of the
body all equate to the ultimate synthesis of man and machine.”

Nice airgun!!!
I would suggest you to add wooden support ,just to avoid distortion of the barrel if it fall or something.

Nice build, sleek, simple, works nicely. Perfect example of keep it simple. One thing troubles me, shooting in the house. You can't shoot outside?
