The Arisaka Low Profile Picatinny Rail is a 5-slot rail designed for M-Lok handguard systems, featuring a reduced height to bring Picatinny accessories closer to the handguard. This model secures with three M-Lok nuts, distributing the stress from larger Picatinny accessories like bipods or vertical grips across multiple M-Lok slots for added stability. **Requires an IP25 or T25 Torx driver for installation (not included).
