Arisaka Defense Offset Light Mount for Surefire Scout Weapon Lights

The  Arisaka Offset Scout Weapon Light Mount is a versatile yet simple accessory for weapon lights. It has been designed specifically for use with the Surefire Scout Light M600 and M300 series weapon lights and other weapon lights that use the same footprint. The mount replaces the stock Picatinny rail adapter included with Surefire lights with a low-profile mount for MLOK, Keymod, and Picatinny handguards.

As shown in the picture below, when used on the side mounting surfaces of handguards the Offset Scout Mount places the light at a 45-degree angle and tucks it in closer to the rail system.

Another benefit of the Offset Light Mount is that it provides three lateral mounting positions for the light body. This allows the user to position the light closer or farther away from the top rail, front sights, or other accessories, and provides a range of approximately 0.240″. When used with the Arisaka 300 Series Light Body or 600 Series Light Body, even more clearance can be gained for larger front sights.

The Arisaka Offset Light Mount is an impressive accessory that offers a range of benefits for weapon light users. Its low profile design, lateral mounting options, and compatibility with a range of different handguards and weapon lights make it a highly versatile and functional accessory that is well worth considering for anyone looking to enhance the performance and functionality of their weapon light setup.

However, it is important to note that it will not fit the handguard profile of the Aero Precision Enhanced Gen 2, SIG MPX, or MCX Virtus (unless using the MCX suppressor width handguard).
