QB79 Tank Block Kit Fits Crosman 2240 Pistol

Barry from The Villages in Florida kindly sent some photographs and information on his Crosman 2240 pistol upgrade project in which he used an Archer Airguns QB79 Tank Block Kit.

Barry installed an Archer Airguns QB79 Tank Block Kit on his Crosman 2240 air pistol so as to be able to attach a 3-5-ounce CO2 paintball tank. And as you can see, it works perfectly!

Bary's words follow: "The most difficult part was getting the holes drilled properly in the tube; got lucky the first time. I guess I could have drilled larger holes to make alignment less critical, but I wanted to make sure there was less chance of leakage. I believe that with the four O rings, that should not be an issue."

"I have installed a B&A Max-Flow valve and the Archer Tank Block Kit. It fits perfectly. My gun has an .177 - 18-inch barrel. Works like a dream. Will be testing fps on my chrony."

"PS I have to give credit to John DiStefano who told me about your Tank Block. He has one, but it will not work with CO2 because it does not have a probe to release CO2 from the bottle."

John thanks from me too! The Archer Tank Block works with CO2, but is not strong enough for HPA use at higher pressures. John's block is designed and manufactured for use with HPA applications.

Barry: thank you!
