Configuring your HPA-powered airsoft gun can get easier these days if Titan Airsoft had their way. They are now on the prototype stages of creating their Titan Airsoft HPA Kit for Version 2 Gearbox Airsoft Guns. You can program the settings using a mobile app which makes it easier to input the settings. Bluetooth is used in making the connection between the FCU of the HPA kit and the mobile phone.
