The ProMag LR-308/SR-25/Ruger Precision Rifle .308 Win magazine is purpose-built for modern long-range platforms and precision rifles chambered in .308 Winchester. Whether you're running a Ruger Precision Rifle, an SR-25, or another LR-308–pattern gun, this 20-round magazine delivers dependable feed and capacity for extended range sessions, tactical competitions, or field work where you need more rounds between reloads.
Made in the USA, this magazine combines rugged construction with precision engineering. The heart of the design is a heat-treated chrome silicon wire spring—the same robust material used in quality mil-spec magazines—wound to exacting tolerances and assembled under strict quality control. Every magazine is checked and double-checked during production to ensure consistent performance and reliability you can trust.
The black phosphate finish protects against corrosion and blends seamlessly with modern tactical and hunting builds. ProMag backs this magazine with a lifetime guarantee against manufacturer's defects, so you can load with confidence knowing your investment is covered.
