FTF/FTE When Running Suppressed

Suppressors can change the way recoil impulse and bolt velocity behave in a direct blowback AR-9 platform. Since AR-9 systems do not utilize a traditional gas system, factors such as buffer weight, recoil spring rate, and bolt mass play a larger role in cycling behavior. These changes in cycling dynamics can also affect how the trigger interfaces with the bolt during operation. If you experience issues such as feeding, ejection, inconsistent reset, hammer follow, or abnormal bolt movement while running suppressed, adjustments to the recoil system may be required to help ensure reliable cycling and proper trigger function.
