Lightweight ARCA Mount for Precision Support
The SRS 4″ ARCA Rail delivers a sleek, low-profile ARCA dovetail that’s strong, versatile, and incredibly light. Manufactured from precision-machined 7075 aluminium, this rail was engineered to be one of the lightest ARCA mounts available while providing full-length slot flexibility for mounting configurations.
Designed to pair with ARCA-style tripod clamps, this 4″ rail lets you quickly interface with tripods for stable shooting support — ideal for hunting setups or positional shooting where a tripod outperforms a traditional bipod. With a maximum hole spacing of ~3.25″, it’s compatible with a wide range of stocks and bottom-metal configurations.
