I have a used GLA Paintball CO2 regulator with solenoid that I no longer use. I tested with no leaks. You are welcome to test it with your own paintball (I no longer have one) if you are interested before you buy. I rather not to ship it, so not going into SNS atm. I have the jbj bubble counter also if needed. The only thing missing is the cover from the low pressure gauge, but I have a cover that you can glue on if needed, there is no damage on the gauge. Another thing is with a little diy, you can turn this into a regulator that can use co2 cylinder if you ever need to upgrade and the adjustable output pressure is 0-60psi. Just get the cga320 stem and some elbow connection from the forum. Price is $100 dollars. Don't go cheap with your paintball with an ASA on/off valve. Thanks.
