he Arisaka Inline Ring Mount is designed to securely attach 1" handheld lights to KeyMod handguards. The mount is especially useful on handguards that feature 45 degree angle mounting flats, such as the BCM KMR, KAC URX4, Mega MKM and MI Gen 3. When used on a 45 degree angle mounting flat, the Inline Ring Mount allows the user to position the light closer or farther away from the top 12 o'clock rail to give clearance for front sights or other accessories. Three positions are provided, allowing an offset of 0.24" from center. The outer diameter of the handheld light sits 0.41" above the KeyMod or M-Lok mounting surface, making the entire unit very low profile. Additionally, the mount can be reversed, allowing further flexibility for positioning your light (it is necessary to loosen the KeyMod nuts and spin them 180 degrees if you intend to use the mount in reverse). Base length is 2.37" and the ring size is 1.00".
The clamping screw for the ring should face away from the handguard when installed. It is necessary to remove and reinstall the ring in the correct orientation for whichever side of the handguard you are using it. A 9/64" and 5/64" Allen wrench, plus T15 Torx driver are required for installation (not included).
