Specifications
Description
The Arisaka M-Lok to M-Lok Adapter (MMA) provides the user with a set of three half M-Lok slots at 40 degrees offset. This is especially useful for handguards that lack M-Lok slots at the 1:30 and 10:30 clock positions. As shown in the product images, the MMA is perfect for mounting a Unity Hot Button to one side of the top rail, allowing easy activation with your thumb. The MMA can also be used on the 6 o'clock M-Lok slots in combination with a vertical grip like our VFG-M to create a grip that angles out to one side, providing more clearance around drum magazines or for use on a light machine gun. The mount is CNC machined from 6061-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Requires an IP20/T20 Torx driver for installation (not included). Recommended torque: 30 inch lbs for M-Lok screws with medium strength threadlocker.
