Well just tested it with a CO2 cartridge and the original piston... worked fine, no leaks. So all thats left is to make a body for this, and eventually a magazine.

Told you a few people laughed a few people cried most people were silent i remembered the line from the hindu scripture

haha. indeed you did o wise JSR.

cuz i can't resist the urge of shooting something, took a few shots while it was at max power, even though it was a 3/8" bearing, so there was considerable blow by. At 10 feet or so, managed to penetrate a 1/4" into a 1" particle board. So hopefully when I make an airtight projectile, power will be better.

Started making actual projectiles today..

I'm sorry for the terrible quality of the picture I couldn't get it to focus on it to save my life.

It's pretty basic, just a short section of the barrel is lubed up, the ball bearing is dropped in and epoxy is poured into it.

Haven't test fired it yet, but it should give a good airtight seal and will be pretty easy to feed via magazine eventually.

Looks good I'd be concerned about the BB breaking off on firing though if you haven't roughened the adhering surface.

it just broke off before even firing... so I will have to roughen the adhering surface of the Ball bearing for the next one.

I'd really rough it up..drill a hole if you can.. bastard cut file/grinder as well

Make sure there's no grease or lube on it too. Hit it with a blow torch to burn it off.

... or just avoid using BBs altogether
