Surefire M340v head question

[Desert Rat]

My question is, can I use a KM2-C head on a 340V? I’m looking to upgrade the power and want to make sure it will thread in and work. Thanks in advance

Pretty sure all of SureFire's heads use the same threads. You can mix and match whatever on them.

I actually have a clone Vampire head coming from Chyna to see if they copied SureFire's threads too lol.

The only difference will be with the new Dual Fuel type lights. The threads and heads are different sizes than the regular Scout based lights.
