Started to work on the main piece, it's 2 1/4" x 1" aluminium channel, a bit rough in places but should work ok.

Many holes to drill

It looks long. Is it repetition?

Just a single shot, the barrel tube is 900mm long at the moment, that's how it came, I will cut it down to about 750mm.

To work to finish the weapon. One more for your collection of pneumatic weapons.
I do not have anything in that caliber, 4.5 mm. I'm thinking of buying a shotgun with rifling to make a small hybrid that is what I design. The only thing that looks like is the 3/16 "steel bb I use on a small combustion rifle.They are fast.

I'm getting an Eraser rail gun vibe, I like it!

Are you aiming for high velocities?

Noooo, I'm aiming at a target and hope something comes out the end of the barrel when I pull the trigger, everything else is a bonus. :P

That's a push to connect fitting at the barrel attachment if I'm not mistaken, which means if you press the blue plastic ring the barrel will come off? Even if the barrel is locked somewhere else that's not a perfect spot for the o-ring to seal against but probably won't leak much.
