I don't think any exist except maybe on Amazon...might not last very long either. Anything worth its salt is gonna be in the hundreds for civilian use (even then, those are good-ish), but that's not to say there might be some on Amazon since they carry mostly chicom products.
People tend to like Green (it's catches your eye) best but they both work equally well. Red is less of a power hog; easier on your eyes too.
You'll have to weigh laser color, run time, and power (brightness) against this most likely. Make sure the rechargeables are replaceable.
I've only seen lasers with a Pic mount...I'd have to go look and see. You can put a Pic rail on an M-Lok
Given your requirements, you might get 10m in the day and 25-75m at night...maybe a little more but not much before it either poops out or the spot is too big to be useable.
Vis lasers are for non-NV and for when the lights go on...don't think he's gonna be clearing rooms anytime soon.
Even then I've seen a lot of "high speed" dudes clowning on vis lasers for any purpose except zeroing a slaved IR laser. I think they can have a spot in your kit, especially if you had to engage indoors with something long that prevented effective use of your sights, but that's a super niche scenario (and not a fight I would take outside of some extreme circumstances). This is all just my opinion though, I'm not a high-speed dude by any means.
Correct, they do have a place. That's why the NGAL pad has a vis override button...for exactly day, lights on and room stuff.
