Description

This ammo is loaded in MAST new cases with a Sierra 220gr. HPBT Match King. The average velocity of the ammo is 950 FPS and was tested with a 16″ barrel with a carbine length gas system.

Note: Velocity will differ with different barrel lengths and individual shooting conditions. This ammunition contains Mil-Spec primers and the use of traditional bolt guns could result in misfires due to a thicker walled primer. This ammunition has shown to have a reliable function in carbine gas as well as pistol gas.

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 and drastically reduce the report from the firearm.
