Variable pump coaxial
I present to you all a simple .30 caliber coaxial piston gun with floating o-ring pump and "custom" trigger. My intent with building any air gun is it must be self contained , no co2 or fridge pump. I learned so much here but noticed the lack of pump guns on the files similar to a crossman pistol I've had for years . I do have a very simple trigger system and grip planned out but right now this shoots incredibly well so im showing it !

Looks cool, what kind of pressure can you generate? By the looks of it I would guess 200 psi max...

Clever.
Wondering where you found the barrel and how you attached it?
Maybe add a butt of sorts to the pump rod ....

come undone
30 bar would be overkill in my backyard!
The barrel is brakeline . I just took some 30 cal. slingshot ammo to the auto store , can't remember
the exact size.
Its all high quality epoxy inside , the barrel has about an inch long plug. The pump tube is simply
another inch of epoxy with a tiny hole drilled thru and a silicone (or rubber ) flap screwed on.
Ah, and the pilot trigger is as simple as an o-ring on a gold construction screw poked thru brass end cap
that was drilled out larger than the screw , allowing pilot venting.

Fantastic work, great to see some out-of-the-box thinking and fabrication

Im always outside-the-box due to being a cheapo ( resourceful ?)
This is genuinely almost bringing a tear to my eye, those epoxy endcaps! *sigh*

I'm really liking the self-contained nature of these creations, it would be a great concept for a cane gun!
For some reason I'm reminded of clide's mini-pump, though the latter being coaxial was more compact.

The execution is different but the concept of a self-contained coaxial is there. Great stuff!
