Area 419 ARCALOCK Dovetail Rail Features The Area 419 ARCALOCK Dovetail Rail addresses a common frustration with standard ARCA rail systems which rely on friction alone and can slide under pressure from a barricade stop. Serrated sides along the rail interface with Area 419 s proprietary clamp design to mechanically lock the rail in place so no movement is possible while the serrations themselves are smooth enough to avoid damaging bags or hands. The rail remains backwards compatible with standard ARCA accessories though it only achieves the locking function when paired with an Area 419 clamp. Machined to the RRS 1.5 inch dovetail standard it is built to work reliably with lever clamps from that ecosystem. Constructed from 6061-T6 aluminum and finished with Type 3 hard coat anodizing the rail is built for durability under the rigors of field and competition use. Every corner is radiused and every edge chamfered on the machine a slower manufacturing process that results in a rail with no sharp edges anywhere along its 12 inch length. M-LOK slots on the underside allow additional accessories to be attached directly to the rail itself and the rail comes with all necessary M-LOK mounting hardware included. Made in-house in the USA from US sourced aluminum the Area 419 ARCALOCK Dovetail Rail is built for precision rifle shooters who demand a rock solid ARCA platform.
