Installation & Tuning Tips
Ensure your barrel’s gas seat diameter is .875" before installing.
Initially set the gas screw with an Allen key to arrive at the baseline where your rifle cycles reliably (with or without a suppressor as your use-case dictates).
Lock in that baseline setting, then use the flip lever switch to change between low/high flow settings during operation as needed—ideal when transitioning from suppressed to unsuppressed, or operating in harsh conditions.
After tuning, confirm reliable cycling, minimal excess gas blow-back, and optimal bolt lock-open behavior with your specific load and configuration.
Perform periodic inspection of the gas block and associated hardware to ensure set screws remain secure and the lever mechanism operates freely.
