Arisaka Defense 40 DEG M-LOK to M-LOK Adapter

The Arisaka M-LOK to M-LOK Adapter provides a set of three half M-LOK slots positioned at a 40-degree offset to give additional mounting locations on M-LOK handguards. It addresses handguards that lack slots at the 1:30 and 10:30 positions and allows accessories to be mounted off-axis. The adapter is useful for mounting a Unity Hot Button on the top rail for thumb activation or for angling a vertical grip when used in the 6 o’clock M-LOK slots. The adapter is finished in anodized black and is constructed from aluminum.
