Arisaka Defense, Finger Stop, Anodized Finish, Flat Dark Earth, Fits M-LOK - SKU: FS-M-FDE - UPC: 601557939524
Product Description
The Arisaka Defense M-LOK Finger Stop in Flat Dark Earth (FS-M-FDE) is a compact, ultra-lightweight forward control accessory engineered to enhance hand placement consistency, weapon retention, and recoil management on M-LOK handguards. Featuring a low-profile footprint, the FS-M-FDE functions effectively as a forward index point, barrier stop, or rear pull-stop between your index and middle fingers, preventing hand slippage toward hot barrels or muzzle devices on short-barreled rifles (SBRs) and AR pistols.
Precision CNC-machined in the USA from 6061-T6 aluminum and finished in a durable MIL-A-8625 Type III hardcoat Flat Dark Earth (FDE) anodized coating, this finger stop weighs under an ounce while offering extreme structural rigidity. Its smooth, bi-directional contour accommodates diverse shooting grip styles, whether using modern C-clamp holds or traditional lower-rail hand placement.
Occupying only a single M-LOK rail slot, the Arisaka FS-M-FDE mounts flush against the handguard without interfering with adjacent weapon lights, laser target designators, or top-rail optic mounts.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fit for all standard M-LOK handguard slots (occupies 1 slot).
- Verify host firearm is completely clear, magazine removed, safety engaged, and chamber confirmed empty.
- Loosen the M-LOK T-nuts on the FS-M-FDE assembly so the gap between the nut and the indexing tabs equals the thickness of the handguard wall.
- Insert the T-nuts into the desired M-LOK handguard slot, ensuring the finger stop rests flat against the rail surface.
- Apply light outward pulling pressure on the finger stop while tightening the IP20 Torx screw to ensure the T-nuts rotate 90 degrees into the locking position.
- Torque the Torx screw to 15-20 in-lbs using a calibrated torque driver.
