Almost Perfect Piston

this is a barrel sealing piston, the barrel is on the left, fill and exhuast are on the right. the point is that this piston will allow a bolt(like the slider by clide) to return easier and wastes absolutly no air. the only downsides are that its expensive, long, and complex.

try to figure it out, if you see any problems with it, or other comments, post.

has this been done before?
