How does the extended booster preform as a flash suppressor? I have not seen reviews or videos on this item.
Via YouTube, it looks like you have shot it in some low/dim light.

The boosters were never intended to work as a flash suppressor, so they aren’t that good at it. The extended one like on mine, mitigates it a little, but there’s still a fair amount of flash.
