Area 419 ARCALOCK 12" Flat Keymod Dovetail Rail

Area 419 ARCALOCK Dovetail Rail System

The ARCALOCK represents a meaningful advancement in precision rifle accessory mounting. Where traditional ARCA dovetail rails rely on friction alone, this system introduces serrated mechanical locking that eliminates movement under field conditions.

Key Features

Mechanical Locking Design

• Proprietary serrated interface works exclusively with Area 419 clamps
• Serrations are engineered for grip without sharp edges that damage bags or hands
• Backward compatible with standard ARCA accessories (though without locking benefit)

Practical Specifications

• 12 inches long—spans the full length of most rifle stock foreends
• Weighs only 4.1 ounces
• Manufactured to RRS 1.5" dovetail standard for universal lever clamp compatibility
• Keymod attachment with all necessary hardware included

Build Quality

• 6061-T6 aluminum construction
• Type 3 hard coat anodized finish for durability
• Every corner radiused and edge chamfered—no sharp points
• Manufactured in-house on USA-made CNC equipment from domestically sourced aluminum

Why It Matters

Anyone who has used a barricade stop on a standard ARCA rail knows the frustration of creep under sustained pressure. The ARCALOCK's mechanical locking system addresses this directly, providing the stability serious precision shooters demand without adding significant weight or complexity.
