Product Description The Area 419 ARCALock Universal Flat Rail is a precision-engineered accessory designed for serious shooters who demand reliable, slide-free performance from their ARCA rail system. Unlike traditional ARCA rails that rely on friction locks - which can slip under pressure - the ARCALock features a proprietary clamp design that mechanically locks the serrated sides of the rail firmly into place, eliminating the frustration of unwanted movement during use. This 8-inch flat rail is machined from 6061-T6 aluminum and finished with a Type 3 hard-coat anodizing for exceptional durability and corrosion resistance. Every edge and corner is fully radiused, ensuring a snag-free, comfortable experience during handling and operation. The rail is fully backwards-compatible with all standard ARCA-style accessories on the market, and while it was originally developed with the Manners Composite Stock in mind, it fits a wide range of rifle stocks featuring an accessible front-action screw or front-attachment point. Made in the USA, this rail is the go-to upgrade for precision rifle competitors and field shooters alike.
