The revolutionary First Strike Tiberius T15A1 PDW airsoft rifle is the new compact HPA airsoft rifle. Just hook up your favorite low pressure air system, run a remote air line from the adjustable PDW stock, and you’re ready to shoot. The First Strike airsoft rifle comes with an efficient mechanical HPA system that has a 2,000+ shot count per air tank (used with 48 cubic inch 3000psi air tank sold separately). The body is made out of a high grade cast aluminum and is manufactured to the tightest tolerances. The T15 airsoft rifle also features a robust valve system that is isolated from the striker/bolt assembly. The operator can separate the upper receiver from the lower receiver safely without the need to de-gas the system, i.e. remove the tank/air source. Also, no batteries are required which means the First Strike T15 airsoft rifle is suitable for play in all types of weather.
