The ARCA rail, formally known as the Arca-Swiss rail, is a mounting system widely recognized in the world of photography but has since become an invaluable component in precision shooting sports. Its design is analogous to a dovetail system, where the accessories slide onto the rail with ease and lock into place with a lever or thumbscrew.

Predominantly constructed from robust materials like aluminum, ARCA rails offer shooters a secure and stable platform. The rails are compatible with a range of accessories, including bipods, tripods, and ball heads, enabling shooters to rapidly attach, detach, or slide these components along the rail for optimal positioning.

The adaptability of the ARCA rail system is further enhanced by its retrofit capabilities. For instance, certain products like the M-LOK® to Arca adapter plate allow users to transform their existing rifle setup into one that is ARCA-compatible.
