I’d call a retailer and ask. Pyramidair will check stock before shipping if you ask them, So will straight shooters and some others. I dont know what serial number is for guns that started shipping with the new valves.
A call to Air Force would probably clear up any other questions. I know that they were out of stock for a while. Maybe they were clearing out old inventory before they came out with the new ones?
Pyramidair probably has the quickest stock turn around so will likely only have new stuff.
Can some post a pic of the old and the new or describe what to look for to tell them apart. When I ordered my condor two weeks ago I said I wanted one with then new valve, well I got #01717 so that not going to fly it even had the return papers in the box from they other guy.
I just know that my Condor is on Crack now. It is insane with the new valve. I’m pretty sure I will have to get the .22 heavy Eun Jins from Pyramid to calm her down.. But this is what I have wanted! Pure Power.
I only take out Feral Cats, Feral Pigs etc.,,,,,
The Power Wheel seems to work just fine as far as velocity adjustment is concerned as well.
