Area 419 ARCALOCK 12" M-LOK Dovetail Rail

Area 419 ARCALOCK 12" M-LOK Dovetail Rail

Area 419 engineered the ARCALOCK system to solve a real problem: standard ARCA dovetail rails can slide under pressure, even with barricade stops. The solution is mechanical locking instead of friction alone.

Key Features

Mechanical Locking System

• Serrated rail sides interface with Area 419's proprietary clamp design for rock-solid, immovable attachment
• Serrations are smooth—no sharp edges to damage shooting bags or your hands
• Backwards compatible with standard ARCA accessories (though locking requires Area 419 clamps)

Practical Design

• 12" length spans your entire stock forend for maximum attachment flexibility
• Weighs only 4.1 ounces—negligible impact on rifle balance
• M-LOK slots on the underside accept any M-LOK accessories
• Includes all M-LOK mounting hardware

Built to Last

• Manufactured to RRS 1.5" dovetail standard for universal lever clamp compatibility
• Made from 6061-T6 aluminum with Type 3 hard coat anodizing
• Every corner radiused and edge chamfered for durability and safety
• Manufactured in-house in the USA using USA-sourced materials and American-made CNC equipment

Note: This rail requires 6 consecutive M-LOK slots for attachment. Stocks with fewer M-LOK slots should use a 12" universal rail with M-LOK attachment nuts.
