M2 (T2) Flash Reducer

The M2 flash reducer (1) pads serve to limit breech flashback, as well as muzzle brake flash and blast overpressure.

The M2 flash reducer consists of a red cotton cloth bag, 4 inches (1 0.16 cm) square, containing black powder and

potassium sulfate or potassium nitrate. The M2 flash reducer, which is a separate item of issue, may be used with M4A1

propelling charge if additional flash reduction is desired. In preparing an M4A1 white bag propelling charge for firing,

one flash reducer is added in front of the base charge and one in front of each increment used.
