Thread: best scope mount for flashlight?

I want to attach a small flashlight to my scope for spotlighting possums at night.
Whats the best kind of mount to use? I see tons of stuff available on the likes of aliexpress.
Ive got a convoy s21A, not sure on the measurements on half the things listed to know if it will fit my light, but want something that has a quick detatch. I see many different types available.
Also I see ones with weaver mounts that could fit on the rifle and holds the light to the side, I dont know whats best, but there might not be enough room for that to fit between the scope mounts or not, depending on the height, etc.
