Leupold Scope Rings
Leupold Mounting Systems
Your mounting system is the crucial link between your firearm and your optic, and it’s where accuracy and performance start. For Leupold’s steel mounts, it all begins with red-hot, Strike Forged steel blanks. Leupold aluminum mounts are machined from aircraft-grade aluminum. This is what it takes to ensure rock-solid repeatable accuracy, shot after shot, year after year. We meticulously machine and polish each mount and after rigorous tolerance testing, we stamp them with the Leupold logo.
STD And DD Rings
STD – Strike Forged steel, precision engineered to match all STD bases. Five heights available. Anti-slip grooves eliminate scope movement in the rings.
DD – One of our strongest systems, designed for the hardest-kicking firearms. The twist-and-lock action ensures a solid connection with the base. Bases accept all Leupold Dual Dovetail rings.
QRW And PWR Rings
QWR – Detachable mounts, crafted from durable steel. The updated industrial design gives you more contact with the base for added stability and easier installation.
PWR – We’ve updated the cross-slot design of these steel rings to be stronger and to give them more contact with the base for added stability and easier installation.
Backcountry Cross-Slot Rings
Backcountry – This updated cross-slot ring design has more contact with the base for even greater stability. Machined from 7075-T6 aircraft-grade aluminum for a lifetime of lightweight, rugged performance.
