im a pnuematic fanatic but i always enjoyed the explosive energy of my first combustion. i think the explosiveness of combustions makes up for the low pressure they produce.

I put my first pnuematic to the test against my first combustion and i think the aerosol beat the ball valve by a little.

the pnuematic was filled to 100 psi, and they had the exact same barrel lengths. the pnue had a 2:1 ratio and the combustion had a .8:1 ratio

now have a pnuematic that spanks my old combustion.

Thats quite a feat! 2460 fps with a pneumatic!Well any ways.PNEUMATIC rocks my world but i do love the combustion boom but cant get over the fun of a pneumatics reliable power and that cool condensation mist that comes out of the barrel after a shot and twice i hace had a "condenastion ring" come out of my barrel and fly about 2 meters which was pritty cool,has this happend to any 1 else?

It happened with my long barrel pneumatic.I wouldn't say that the sound from the pneumatic is uncool.

i think combustion is very coowl.
i like the bang with it, and it would be a lot coowler becaus dificulter to make it semi / full auto.

also with combustion you can experiment more, becaus they doens't coast so mutch.

also when you have got the right mixture of air and butane it could fire very fast and whit a large bang.

buth still pneumatics are also coowl and easy to mod.
