The PTR 91 Magazine .308 Win 10-Round in black is a factory magazine purpose-built for PTR Industries' AR-pattern rifles chambered in .308 Winchester. If you're running a PTR 91 or compatible platform rifle, having reliable, purpose-made magazines on hand is non-negotiable—this one delivers the durability and consistent feeding you need for hunting, tactical training, or extended range sessions.

Built with aluminum construction and a steel spring, this 10-round magazine is engineered to handle the pressures and tolerances of .308 ammunition without compromise. The aluminum body keeps weight down while maintaining the structural integrity needed for repeated loading, unloading, and field use. The steel spring mechanism ensures smooth, reliable feeding every time you chamber a round—no chatter, no hesitation, no surprises downrange.

The 10-round capacity strikes a practical balance: it's legal in states with magazine restrictions, yet holds enough rounds for practical hunting, sport shooting, or training scenarios. The black finish blends with most modern rifle setups and resists corrosion under normal field conditions. Whether you're building out your PTR 91 platform or adding backup mags to your rotation, this factory magazine is a straightforward, proven choice.
