Arisaka Defense Finger Stop Picatinny Black

Arisaka Defense Finger Stop for Picatinny Rails

The Finger Stop represents thoughtful accessory design—a minimal control device that solves real problems without adding unnecessary bulk to your rifle.

Design and Ergonomics

This stop was engineered with a slim profile that naturally positions between your index and middle fingers. Mounted forward on the handguard, it stays out of the way during transitions to kneeling or prone positions, where your support hand naturally moves rearward. The wider profile also functions effectively as a rear hand stop for shooters who prefer that location.

Practical Functions

Beyond finger positioning, the Finger Stop serves multiple purposes:

• Barrel Protection: Acts as a forward limit to prevent fingers from slipping onto a hot barrel or suppressor during extended shooting sessions
• Barricade Support: Provides a stable reference point when shooting from improvised rests
• Handguard Security: Particularly useful on shorter handguards where finger placement becomes critical

Installation and Specifications

The stop mounts directly to 1913 Picatinny rails via two nylon-tipped set screws. Due to its low-profile design, installation requires sliding the stop onto the rail—a process that demands precise rail specification compliance. Torque set screws to 15 inch-pounds. The anodized black finish provides durable corrosion resistance.

Note: Out-of-specification or damaged rails may present installation difficulties.
