The Arisaka 3" M-LOK Slim Picatinny Rail with QD Sling Mount Socket is a precision-machined handguard accessory that lets you mount standard Picatinny equipment—optics, lights, lasers—directly to M-LOK slots on your modern rifle or carbine. Made in the USA from 6061-T651 aluminum and hard-coat anodized to MIL-A-8625 Type III specs, this slim rail spans three M-LOK slots and includes an integrated anti-rotation QD socket for sling attachment, making it an efficient alternative to bulkier rail systems when you need Picatinny real estate without excess footprint.
The rail comes with both standard and short-length hardware to clear gas blocks and other barrel contours that might otherwise interfere with installation. CNC machining ensures precision fit and repeatable torque specs—tighten to 30 inch-lbs on metal handguards or 15 inch-lbs on polymer. This is a practical choice for shooters running modern M-LOK handguards who want modular light, laser, or optic mounting without committing to a full rail system.
Arisaka's approach here is straightforward: solve the clearance and compatibility headaches that come with mixing rail styles. Pair this with an Arisaka Rail Slider if you need one-handed indexing and locking, or use it as a standalone M-LOK-to-Picatinny adapter on any compatible handguard.

Yes—the rail mounts directly to M-LOK slots. The 3" length covers three full M-LOK slots. Hardware is included to secure it; use standard screws on metal handguards and short screws if a gas block or other contour creates interference.
The rail features a full 1913 Picatinny profile, so any standard Picatinny-mounted accessory—tactical light, laser, magnified optic, or other equipment—will fit.
No. The rail includes a QD (quick-detach) socket for sling attachment, but the sling itself is sold separately. The socket is anti-rotation, so it stays indexed once seated.
Tighten to 30 inch-lbs if your handguard is made of metal, or 15 inch-lbs if it's polymer, to avoid over-tightening and damaging the mount.
