Smart Parts 2002 All American
20 oz CO2 with Smart Parts on/off valve
Saves you at least 100 shots everytime you take it off!
not too expensive $17
Smart Parts is a great company, very good products.
You have to take the old valve off you tank so you can put this one on
(a royal pain in the a$$)
Very good for the price. Just remember to turn it ofdf like 5 - 7 shot before your done because the CO2 that is still in your gu will get out. I give it a 9 because it's a pain to take out the old valve. There was a lot of loc tite on mine.
