The Arisaka 3-Slot M-LOK Picatinny Rail with QD Socket (brand part no. RS-RAIL-3M) is precision machined specifically to pair with the Arisaka Rail Slider, giving shooters a proper 1913 Picatinny mounting surface on an M-LOK handguard. An anti-rotation QD socket is built into one end for a sling swivel or similar accessory, and the rail includes both standard and short screws to work around gas blocks or thicker barrel contours that would otherwise cause clearance issues. Length is measured by how many full M-LOK slots the rail covers; this 3-slot version suits shorter handguards or more compact mounting locations.
