In Stock Really Right Stuff USR-240 240mm Universal SOAR Rail with AI Key Slot Hardware Kit
The Really Right Stuff USR-240 Universal SOAR Rail is a lightweight, precision-engineered mounting solution built for exceptional strength and versatility. Machined from 6061-T6 aluminium, it features an R-LOCK compatible 1.5-inch dovetail while maintaining full compatibility with traditional RRS quick-release systems. Supplied with the Accuracy International Key Slot Hardware Kit, it integrates seamlessly with AI chassis systems, while ambidextrous safety stops and a modular mounting design provide secure, repeatable positioning for precision shooting and tactical applications.
The Really Right Stuff Universal SOAR Rail (USR) with AI Key Slot Hardware Kit is a cutting-edge mounting solution designed to deliver maximum versatility and precision for modern rifle systems. As the first rail in RRS's line of R-LOCK compatible mounting platforms, the USR integrates a 1.5" dovetail that works seamlessly with the R-LOCK standard, while remaining fully backward compatible with traditional RRS quick-release clamps and heads.
Constructed with 6061-T6 aluminium, the USR is lightweight yet shear-resistant, with geometry optimised for ease of manufacturing, even without CNC machinery. This makes it a practical solution for both professional gunsmiths and competent enthusiasts. The rail features precision-drilled 5.5mm safety stops milled along both edges, enabling ambidextrous use, and R-LOCK holes spaced no less than 10mm apart. These provide reliable, repeatable locking points and support traditional mounting mechanisms.
Its modular slotted mounting system ensures broad compatibility, accommodating various hardware kits for different stock types. This version includes the Accuracy International (AI) Key Slot Hardware Kit, enabling seamless integration with AI chassis systems. Anchors slide within the rail slots and are held captive with an O-ring for a secure, adaptable fit.
Designed as a low-profile, semi-permanent rail, the USR must be mounted flush to a flat surface to maintain performance. It is not intended to be cantilevered beyond a rifle's foregrip, and improper installation on uneven surfaces may compromise its integrity.
