The Ninja 50/4500 tank is made specifically for tournament level paintball players.
This product includes the Ninja Pro V2 SLP Regulator which has a ball bearing design that replaces the depressing pin for more durability and better airflow. The Pro V2 can be rotated 360 degrees to ensure proper gauge and fill nipple orientation.
The 50 cubic inch, 4500 PSI tank will get you about 900-1000 shots off one fill. This is great for any competitive or scenario player.
