The Patented Arisaka Offset Scout Mount is designed specifically for the Surefire Scout Light M600 and M300 series weapon lights, the Modlite PLH and OKW weapon lights, the Arisaka 300, 600 and 18650 Series Lights, the Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), and Olight Odin. It replaces the stock Picatinny rail adapter with a low profile mount for LWRC direct thread handguards. The Offset Scout Mount is very low profile at less than 0.20"" thick. When used on the side mounting surfaces, the Offset Scout Mount places the light at a 45 degree angle and tucks it in closer to the rail system. Oriented upwards, the light is located at approximately the 1:30 or 10:30 clock positions. Oriented downwards, the light is located at approximately the 4:30 or 6:30 clock positions. The Offset Scout Mount also provides three lateral mounting positions for the light body, which allows the user to position the light closer or farther away from the top rail, front sights, or other accessories. Three positions are provided, spanning 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.

GEISSELE SMR 416 OFFSET MOUNT The Patented Arisaka Offset Scout Mount for Geissele SMR 416 handguards was developed at the request of a United States special operations unit. This is a contract overrun, with a very limited number available for civilian sales. The Offset Scout Mount attaches directly to the threaded inserts on the Geissele SMR 416, eliminating additional Picatinny rails and Picatinny mounts. Three lateral light positions allow the user to tuck the light closer to the top rail or gain clearance around top rail mounted accessories like laser illuminators. In particular, there is enough clearance for the larger Modlite OKW and PLH heads to fit next to the NGAL, LA-5/PEQ, AN/PEQ15 and ATPIAL-C. It will also allow lights to clear the QD lever on the Steiner DBAL I2, A3, and D2. In addition to three lateral light positions, the mount also allows fore and aft adjustment so the user can fine tune the location of the light to their setup. Length: 2.20" / Weight: 0.9 oz including hardware Hardware: Two 10-32x3/8" Torx flat head screws, two 8-32x3/8" Torx flat head screws.
