Introducing the Arcalock dovetail rail system, a groundbreaking advancement in precision rifle stability. At Area 419, our dedication to innovation leads us to enhance existing products and develop new technologies. With the increasing popularity of ARCA rails in precision rifle applications, we saw a need for improvement. Traditional ARCA rails, while effective, often depend solely on friction, which can result in slippage under pressure, particularly when using a barricade stop. Our solution is the Arcalock dovetail rail system. The Arcalock system revolutionizes dovetail technology by integrating a mechanical locking mechanism that guarantees unmatched stability and security. This cutting-edge design prevents unwanted movement, offering shooters the confidence and precision they require. Whether in a high-stakes competition or practicing at the range, the Arcalock dovetail rail system ensures consistent performance and reliability. Discover the future of precision rifle technology with the Arcalock dovetail rail system, where innovation meets excellence.
