Arisaka Defense 600 Series Weapon Light Body Black. One of the best things about these Arisaka Defense gun lights is that they are MINT quality without any noticeable side "spill" over from the M600 Scout Light. The reason you can use this body is if you have an existing Scout Light mount with a square lug interface and these are compatible with both M600 Scout Light tailcaps and heads as well as aftermarket ones. The great thing about these light bodies is that you can turn them into an entirely new weapon light by replacing the head tailcap and mounting screws. The only thing you need to worry about is securing it to your weapon since the Arisaka 600 Series Light Bodies are MINT quality.
