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. We recommend our Valken SMAG 140rd Mid-Cap airsoft magazines for use with the T15A1 PDW rifle.
