Surefire M300 vs 600

[nate89]

Holy necropost batman!

[Uprange41]

Just picked up a new Surefire M300c mini scout light and it didn't come with a female tell cap and I need on I believe the part I need is a Surefire Part Black Replacement Cap for M300 & M600 "UE-BK"... Can someone please confirm that this is correct or not thanks.

Necro post indeed.

But yes, assuming you want to run their pressure switch, you need UE-BK.
