The rule states that tanks not exceeding 2 inches in diameter, and 2 feet in length are exempt. The Ninja 13/3000 is 2 inches in diameter, meaning it never has to be tested.

The rule for hydro testing exemption is less than 2" in diameter AND less than 2' in length. This tank is just over 2" I believe, and is therefore subject to testing. The only tanks I am aware of that are exempt are the 3.5oz co2 tanks.

this tank feels awesome on a pump gun and gets about 100 shots per fill
AND IT NEVER NEEDS REHYDRO'D because it is under 3 inches in diameter
