Area 419 Firearms LLC Arcalock 12in Flat Keymod Dovetail Rail

The Area 419 Firearms LLC ARCALOCK 12'' Flat Keymod Dovetail Rail represents Area 419's commitment to advancing ARCA rail technology by delivering a mechanically locked solution that prevents movement under pressure, as the rail is designed to lock only with an Area 419 clamp. This 12-inch dovetail rail features serrated sides that interface with the proprietary clamp to secure the rail without damaging bags or hands, while remaining backward compatible with standard ARCA accessories. Crafted from 6061-T6 aluminum and finished with Type 3 hard coat anodizing for durability, it weighs just 4.1 ounces yet provides full use of the stock forend with the convenience of a 12" length. Made in the USA from USA-sourced aluminum on USA-made CNCs, the rail adheres to the RRS 1.5" dovetail standard to ensure lever clamps work reliably. Keymod attachment hardware is included, and every edge is radiused with chamfered corners for a refined, hand-friendly profile. This rail blends Area 419's engineering refinements with practical battlefield-tested performance, offering a robust, lightweight platform for precision setups where secure locking and modular versatility are essential.
