Area 419 ARCALOCK 12in Flat Keymod Dovetail Rail

The Area 419 ARCALOCK 12-inch Flat Keymod Dovetail Rail is a 12-inch ARCA-style dovetail rail designed for precision rifle forends. It employs serrated rail sides and a proprietary clamp interface to create a mechanically locked interface when used with an Area 419 clamp. The rail remains backwards compatible with standard ARCA accessories but provides locking only when paired with the Area 419 clamp. KeyMod attachment points are integrated and the necessary hardware is included.

Key Specifications

• The rail measures 12 inches to provide full-length coverage of the stock forend.
• Constructed from 6061-T6 aluminum for structural stability.
• Finished with Type 3 Hard Coat anodized surface treatment for added durability.
• Built to the RRS 1.5-inch dovetail standard for compatibility with common lever clamps.
• Serrated rail sides interface with Area 419's proprietary clamp design to mechanically lock the rail in place.
• The rail is backwards compatible with standard ARCA accessories but will not provide mechanical locking without an Area 419 clamp.
• KeyMod attachment hardware included for mounting compatible accessories.
• Serrations are not sharp and the rail features radiused corners and chamfered edges to avoid damage to bags or hands.
• Made in the USA from USA-sourced aluminum on USA-made CNC machines.

Engineered for applications where a stable, repeatable interface matters, the ARCALOCK 12-inch rail provides a low-profile, lightweight platform for mounting bipod/bag interfaces, tripods, and accessories. Its ARCA compatibility, mechanical locking interface (when used with the Area 419 clamp), and durable Type 3 finish make it a practical choice for range and field setups that demand consistent, robust performance.
