From seeing the bad guys to looking for a trail, you don't want to be left in the dark. If your AR is wearing a KeyMod or M-LOK rail, an Arisaka Inline scout mount is your answer.

One More Gadget Won't Kill You.

I know, it's easy to go overboard when it comes to toys. There's lasers, scales, bi-pods, sights, and you want all of them. However, if you can't see your target, all those other things won't help you at all. The Arisaka Inline scout mount has a low-profile. That way you can keep your light source close inline to the rifles bore. Any place you have an open M-LOK slot, you can attach this M-LOK light mount.

Next In Line

Most shooters like to have their Surefire Scout light sitting as close to the muzzle as it can get. As long as you have clearance for your front sight, you can clamp the Arisaka M-LOK light mount right up front. You have to think about the real estate available on your rail. As our weapons grow shorter, the available room quickly disappears. That's why you should consider this M-LOK light mount. The mount replaces the stock Picatinny rail adapter, and it opens up options for mounting spots. Hey, you KeyMod fans out there don't get upset. The Arisaka Inline scout mount is also available in a KeyMod version.
