Really simple question I can't find a straight answer to on CPF (god that place is a mess these days).

Can I mount an M300 Scout Head to an M600 body?

Specifically thinking this head: https://malkoffdevices.com/collections/surefire-drop-ins-for-e1-e2-and-scout-lights/products/e1-scout-m300-1cr123-head

On this body: https://www.surefire.com/products/illumination/weapon-lights/m600aa-scout-light-weaponlight/

See edit

Yes, threads are the same, just match your battery voltage.

*The Dual Fuel Scouts have a larger than standard E Series thread. Now I see that is an AA body, I have no idea...

Call Gene at Malkoff. He will set you up.

Wouldn't this require a spacer or dummy cell?

Why not use one of the E2XT heads on the 600 body?

My assumption is that RR wants single 123 performance, out of 2 AA batts, for easy logistics

Exactly.

I'm hoping to move entirely away from CR123/18650/16650 this year. Moving strictly to a combination of NIMH AA & AAA and 14500 LiOns. If I need more power I can through a 6-9v head on the M600 body and stuff it with two 14500s (generating about 8v).
