I'm yet to see a light that had a body which facilitated direct mounting to KeyMod slots personally, the closest things I've found are certain mounts which replace the normal picatinny mounts on SureFire scout lights (and presumably the clones). If your gun does have KeyMod up front but isn't supplied with any rail bits that is certainly a slight downer value wise, however the same gun with a metal forend that had picatinny on all 4 sides would probably have cost quite a lot more in the first place before you even get to the fact it weighs more and to most people isn't as ergonomic (in terms of shape/size and the cheese grater effect).


Matching up the rail pieces to the gun in terms of manufacturer is the safest bet. Some airsoft companies KeyMod is cut to the same spec as the real thing, but a lot aren't and it's often impossible to tell before actually purchasing the product in question. If whatever light you end up buying can't mount to the 12 o/clock rail, I'd recommend sticking to the KeyMod sections by the same brand as your gun.
