Product 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. 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 Arisaka's 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.

Features
  • Length: 2.2";Weight: 0.6 oz"
  • Hardware: Two M-Lok nuts, two 10-24x5/16 Torx button head screws"
  • Made in the USA
