New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

The Polarstar UGS Type 1 12g CO2 Milspec (RS Spec) offers the best of both worlds with the performance benefits of an HPA system while retaining the familiar look and function of an adjustable AR-15 stock. With a compact design that shares the same internal components as Polarstar's larger regulators, this system can deliver top-notch performance with a minimum output pressure of 40 PSI and a maximum output pressure of 130 PSI. The UGS Type 1 12g CO2 Milspec is compatible with 12g CO2 cartridges and can accept up to 900 PSI, making it suitable for use with standard output HPA tanks as well as SLP (SLP recommended). The system's interface with airline (6mm OD x 4mm ID) ensures smooth operation, while the compatibility with standard 2" diameter HPA tanks adds to its versatility. The simple zip-tie lockout/tournament lock provides added safety and convenience, and with only two o-rings in use, maintenance and reliability are a breeze. Please note that the Polarstar UGS Type 1 12g CO2 Milspec is not compatible with the Fusion Engine.
