Hi all!
Does anyone have any info/experience with these systems? http://gaspiston.com/ Are they quality? Thanks! |

I haven't kept up on them, but I know there are a lot of threads about them in the piston forum. You may get some responses from people that have them. If I recall they have only been out for about six months or so.
