| | Sheridan air gun constant air/12 gram question
I remember that cooper t invented an "adapter" of sorts for the Sheridan air rifles that took 12 grams cartridges. This adapter replaced the 12 gram and sat inside the valve tube (bottom tube) and it could be filled with CO2 repeatedly. It allowed for 2 ounces of CO2 to be stored in the bottom of the valve tube because the adpater itself was like a very skinny tank of co2. Does any one have one still? I'm trying to get more information on it. Pics would be super.
