Ultra-Light Tactical ARCA Rail for Precision Tripod Support
The SRS Tactical 4″ ARCA Rail is an ultralight and slim ARCA-Swiss mounting solution crafted for shooters who want a clean, minimalist base for tripod support without excess bulk. Precision machined from high-strength aluminium with strategically cut lightweight pockets, this rail maintains structural strength while keeping your rifle’s weight down — a key advantage for tactical, precision, and backcountry shooters.
At 4″ overall length and just ~1.3 oz, the Tactical ARCA provides a stable ARCA dovetail interface for attachment to ARCA-compatible tripod heads and accessories. Its maximum bolt spacing of ~3.25″ ensures compatibility with a wide range of stocks and bottom metal configurations.
