Description
King Arms M3 Tactical Illuminator BK
The King Arms M3 Tactical Illuminator is a black weapon light modelled on the well-known M3 tactical light style, designed to clamp onto a 20mm rail. It gives you a bright beam to identify targets in dark buildings, night games and woodland under cover, and it looks the part on a pistol, SMG or carbine.
King Arms is a respected Hong Kong airsoft brand known for replicas and accessories. This illuminator is listed as a toy-gun accessory, making it a sensible choice for players who want a realistic-looking light without the cost of a firearm-rated unit.
Using a weapon light
A light on your replica helps you see into dark rooms and corners, check targets before you shoot and dazzle opponents at close range in CQB. The switch on the M3 style light can be used momentarily, so the light only comes on while you press, or left on constantly, which gives flexibility depending on whether you want to stay hidden or light up a room.
Use the light in short bursts in games: a constant beam shows everyone where you are.
Mounting and power
The light clamps to a standard 20mm rail, so it fits most railed pistols, SMGs and rifle handguards. Retailer information indicates it runs on two 123A lithium cells. Always check that the clamp is tight before you play, as knocks against walls and barricades can loosen a clamp over a day of play.

Compatibility
Fits replicas with a 20mm accessory rail. On pistols, check there is enough rail length ahead of the trigger guard, and remember that a light may stop the pistol fitting a standard holster. Light output and bulb type are not stated in our listing.
Care and maintenance
Remove the batteries if storing the light for a long time. Wipe the lens with a soft, dry cloth and keep the threads and battery contacts clean. After wet games, dry the light thoroughly and check the clamp screws are still tight.
Use good quality 123A cells and replace both at the same time.
Who is it for?
A good choice for players who want a realistic M3 style light for CQB, night games and themed builds on any replica with a 20mm rail.
Please note: Never shine a weapon light directly into anyone’s eyes at close range, and follow your site’s rules on lights. Replica not included.
