Review on HK Army Paintball Aluminum HPA Tank - 48/3000 - Olive Blue: High-Performance Regulator Included! by Ronald Noel

As stated in title, item arrived in less than 24 hours with a water test date 5 months earlier. The tank arrived with some scratches on the bottom that looked like it had been dropped while packing. It doesn't affect performance, but I'm concerned it might affect the integrity of the tank. It hasn't been possible to use it on a large scale yet, but I don't understand why this tank isn't working as intended.
