The Arisaka Low Profile Picatinny Single Rail is a 5 slot Picatinny single rail for KeyMod handguard systems. It offers a reduced height to pull any Picatinny accessories closer to the handguard. The 5 slot model connects with three of BCM's patented reverse threaded KeyMod screws which will spread the increased stress of large Picatinny accessories like bipods or vertical grips over more KeyMod slots.
