This Umarex Komplete PCP Tank gives you an easy way to turn your Umarex Komplete into a standard PCP rifle so you can fill it using a normal HPA (high pressure air) source like a hand pump or compressor. You'll like that you can decide if you want to use NitroAir cartridges for convenience and portability or a separate fill source for value and performance. This PCP tank gives you a feature many shooters ask for with its rotating pressure gauge block. You can turn it until you can see it easily to monitor the fill pressure and then fill the tank with air to hold the gauge block in place with air pressure. You'll also appreciate that you get performance and consistency at least as good as you do when using NitroAir cartridges, and that you get plenty of shots per fill because of the air capacity of 132cc and the fill pressure of 4500 psi. If you're in the market for a simple way to switch your Umarex Komplete into a traditional PCP air rifle and back without needing a whole new airgun, get the Umarex Komplete PCP Tank at Airgun Depot now.
