Arisaka Defense Side Scout M-LOK Mount Black. It replaces the stock Picatinny rail adapter with a low profile mount for M-Lok handguards and tucks the light underneath either side of the ATPIAL laser/illuminator series including the ATPIAL-C AN/PEQ15 and LA-5/PEQ. It will also allow the light to clear the QD lever on the Steiner DBAL i2 a3 and d2. As a bonus it also works nicely on the Sig MPX PCC and MCX Virtus M-Lok handguards. A T9 Torx driver is required to remove the stock Picatinny mount from Surefire Scout Lights. Use the Side Scout Mount to secure your Scout Light to your M-LOK handguards.
