Area 419 Arcalock Features The Area 419 Arcalock rail uses serrated rail sides that interface with the company s proprietary clamp design to mechanically lock the rail in place eliminating the slop and movement that standard Arca rails can allow. The serrations are designed to grip without being sharp so they will not damage gear bags or the shooter s hands during handling. Machined to the RRS 1.5 inch dovetail standard the rail remains backwards compatible with standard Arca accessories though it will not lock in place without Area 419 s matching clamp. At 6 inches long and just 2.2 ounces it adds a precision mounting interface without meaningfully increasing the overall weight of a rifle build. Every corner of the rail is radiused and every edge chamfered on the machine a slower process that Area 419 considers the only correct way to eliminate sharp edges and snag points. The rail is finished with a Type 3 hard coat anodize for long term durability against the wear and handling a rifle sees in the field or on the bench. Made from 6061-T6 aluminum entirely in the USA from USA sourced material on USA made CNC equipment the rail reflects a commitment to domestic manufacturing quality. It ships complete with all M-LOK mounting hardware making installation straightforward for any shooter outfitting a chassis rifle with a dependable Arca interface.
