IIRC a lot of PEQ boxes come with unregulated (power wise) visible (red/green) lasers that can possibly damage peoples eyes and some even come with IR lasers which are
extremely dangerous as it's not visible to the naked eye and your body loses it's 'blink response'. Lasers are also banned at the majority of fields due to people being cunts with them (shining them into peoples eyes). Generally speaking, they really have no use in airsoft as far as i've seen.
I'd simply suggest just getting a dedicated weapon light.
If it's the aesthetics you're after, i'd suggest getting a battery peq box. It's the same shell, just with no internals.
If you're dead-set on getting a PEQ, a gun I bought comes with a
generic Amazon PEQ which has a very visible red laser and a decently bright flashlight to boot but has nothing on my dedicated Olight branded weapon light which is like turning on the sun when playing at an indoor field. It's got the IR Laser/IR illuminator which you should absolutely never ever use. I never intend on using this thing and have removed the batteries.
While the label says the lasers are both 5MW power, I wouldn't trust it. 5MW is the strength where it takes approx 10 seconds to damage the eyes. Lasers above this strength can be almost instant and lasers
below 5MW can still damage the eyes permenantly after prolonged exposure.
