New Piston BB Gun

I just recently finished this bb gun. It has a piston made of hot glue attached to what is a hammer that strikes the BB in the barrel. I will glue the casing together and give it a new paint job soon but I'm going on a trip so it will be about a week. These pics should explain it all.

No, the barrel is all thread and I am going to cut the barrel and put in a t connector for a gravity fed mag.

Its like the blowforward breech system. But I think this one has less turbulance as the path of the air is a straight line. I think your piston parts look a bit too heavy though. I mean u dont wanna loose energy by pushing that piston forward> u want to use it to propel the projectile.

It's pretty much
the same thing.
You'll be needing a longer barrel for significant power at compressor pressures though.
