ProMag Magazine LR-308, SR-25, Ruger Precision Rifle 308 Winchester Polymer Black

If you shoot a .308 Winchester rifle and you're tired of swapping magazines every few rounds, the ProMag Polymer Black Magazine for LR-308, SR-25, and Ruger Precision Rifle platforms offers the extended capacity you've been looking for. These high-capacity .308 magazines are built for shooters who want more trigger time and fewer interruptions—whether you're running drills at the range, working through a practice session, or simply stacking rounds downrange. Available in 30- and 40-round configurations, they fit standard DPMS and SR-25 pattern rifles, giving you real flexibility in how you set up your loadout.

Construction matters, especially when your magazine is your ammunition's last stop before the chamber. ProMag engineered these magazines from DuPont Zytel polymer, a material proven to handle the rigors of repeated cycling and field use without failing. The spring is equally serious—heat-treated chrome-silicon wire throughout ensures consistent feeding pressure cycle after cycle, even as you run extended strings of fire. And they're made in the USA, which means quality control from start to finish.

The all-black finish is straightforward and durable, designed to blend with modern rifle setups without any aesthetic nonsense. Whether you're running a precision rifle for competition, a tactical platform for training, or a hunting rifle where a reload might cost you a moment, these magazines deliver the round count and reliability you need when you need it.
