The Malkoff MDM4 Adapter will fit most Surefire Millennium Series Lights including the M3, M4, M6, M500, M961, M962, M900, and M910. The M900AB and M910AB (rail mounted vertical grip weapon lights) may additionally require a spring for the tailcap so the batteries can be installed with the negative toward the tailcap.

This Item is Covered by Our Lifetime Warranty.
Things to Know Before Purchase:
The MDM4 WILL NOT FIT the Surefire M951. For that model please see the Malkoff M61.
The MDM4 will allow for the use of a Malkoff M Series Drop-in in any Surefire incandescent light which uses the stock incandescent MN10, MN11, MN15, MN16, MN20, MN21, MN60, or MN61 lamp assemblies. Please check your bulb before ordering.
The MDM4 will physically allow any Malkoff M Series Drop-in to fit the above listed lights. However, please be sure to check the voltage requirement of the chosen Drop-in against the voltage of your light for compatibility.
