Nice find, I wish I found one.

Not sure exactly how old it is, but it's not new.
I think it is a rare find. I have not seen many.
IMO $100 is a great deal.
I believe the MicroValves are Classice Valves and will work on CO2.
It should be accurate enought, you only really need like 6-8 in. After that it is compensation for a smaller... yeah, large barrels are for show.
My Classic does chuff when shortstroked so I assume it is normal.

Nice find!

I had one a while back...it was fun to fool around with. Just don't use it with brittle paint and you'll be ok. The short barrel means you have to crank up the reg pressure to get the gun to fire at normal velocities, and it can be hard on paint.

Definately a great find, and you got it for an excellent price too. I'd put it in the neighborhood of $200, though it doesn't mean it would bring that much if you sold it (market's kinda flooded).
