Upgrade your precision rifle setup with Really Right Stuff’s line of Universal SOAR Rails! This accessory is semi-permanent, utilizes a 1.5” dovetail, and is fully compatible with the R-LOCK standard, but still maintains backward compatibility with Really Right Stuff’s quick-release clamps and heads. It features 5.5mm safety stops on both edges of the rails for ambidextrous use, and the R-LOCK holes are positioned 10mm apart as safety stop locations along the rail at a tightly controlled distance from the edges. The Universal SOAR Rail features a modular slotted mounting system to provide a wide range of compatibility across countless types of devices. In addition, the Universal SOAR Rails is available in 4 different hardware kits: one for wood/composite stocks, one for chassis systems with tapped holes, one for Accuracy International’s Key Slot System, and one for M-LOK compatibility.
