Are laser sights visible to enemies in matchmaking?

I haven't been playing Siege for too long, and I initially put laser sights on all weapons, but I realized I never see any enemies' laser sights. Is this because you can't see enemies' laser sights or just because not many people use them? If they are visible to enemies, can you see the dot that hits surfaces or only the laser coming from the gun if you're looking at an enemy?


Yes they are, they can go through windows too.
