hope you like my new airgun, it runs 30 bar regulated CO2, and shuts 6 mm steel BB.
not yet finished, still needs grinding , sanding and polishing
The CO2 comes through a high pressure hose to the back of the mechanism.
Better pics soon. THX

Looks good, love the way you put the reloading mechanism together :) At 30 bar you must be getting very decent power, kudos.

That system seems pretty nice but do you have orings on your reload piston. Also do you think that a rubber washer and sping return would make your reload system better or semi auto :wink: so you must not like videos?

I have tried the push forward loading mechanism, that was the initial design, but it turnet out to be too much power and it splits out the bb cought in between.
No o-ring seal, it's a tight fit , so very little gas escapes.
It's definetly not the final version of loading mech., but it's the current one :P



P.S.
no vids because I didn't had the time

I can't make out if the pilot is a pop-off or a hammervalve..or even a slidevalve..

But I like your style..

I tried my second atempt of a push-forward loading mech, the result was prety decend, considering the loading works , the bb's don't rush all at once to the barell, they don't get crushed in between, BUT the fps went from hero tfo zero :P, can't even pierce through a can from 2 feet away

Maybe you can change to this and see if the fps is effective again :)

maybe you can use some modification here

Add a piston rubber seal so the air doesn't leak through the loading chamber and use another spring to push the BBs forward and in the barrel
