This product is optimized for all Barrel lengths, utilizing a pistol length gas system.Please note: The reduced pressures associated with subsonic ammunition can affect the proper cycling of gas operated firearms. Subsonic ammunition is best used with a suppressor. Suppressors create more back pressure and help achieve full cycling of the gas operated system. We cannot guarantee proper cycling if not using a suppressor and a pistol gas system  Due to Noveske's extremely tight tolerance match grade chambers, we will be unable to guarantee functionality of this product in those firearms.
