Weltool W65 Body
The Weltool W65 weapon light body can use 1 18650 lithium ion battery or 2 CR123A batteries (depending on the light head voltage requirement), aluminum alloy material, the surface is anodized, black and FDE colors are available.
The tail of the Weltool W65 body can be fitted with Weltool TC68, TC69, TC70 and other Tailcaps. It is also compatible with surefire Z68 Tailcap, DS00 or UE Rear Cap, so you can use the corresponding Remote Switch such as surefire ST07.
The front of this Weltool W65 body can be fitted with Weltool LH1, LH2, LH3, LH4, LH5 light heads, and it can also be compatible with surefire M600DF KE2-DF heads.
Mounting holes on the W65 body can fit Weltool PM4 mounts, and are compatible with Surefire RM45, AMERICAN DEFENSE MFG AD-SF, and some corresponding rail mounts produced by Arisaka Defense, MAGPUL and Unity Tactical, but surefire M75 cannot be used.
Tip: V2.0 version is more suitable for SF KE2-DF light head
No reason to spend $70 - $80 on an 18650 or DF body from Surefire, Modlight, etc. I've had them all and this is as good as any for half the price.
