    ‍ ‍Additional warnings

     All power (Joules) variants were measured with 0.32g BBs. Power is adjustable at all times.

     Comes with a US-Spec HPA connector (HPA Variant).

     Allow a break-in period of ~200 BBs for the gun to settle in.

    Avoid pulling the trigger without a magazine inserted. The magazine provides support for the valve knocker, extending its lifetime (Gas variant).

     Only connect the HPA line with an open bolt to prevent a negligent discharge. See the Academy safety video for more information.

     Bolt lockback function on HPA version might not lock back reliably out of the box as the system is fine-tuned to the gas variant. HPA bolt lockback will get better over a break-in period. 

     For the HPA variation, we recommend between 120-160 PSI.
