ProMag AR-15 5.56mm/.223 Rem Magazine - A Testament to Reliability

The ProMag AR-15 magazine is a hallmark of American craftsmanship, designed for those who demand unfaltering reliability and performance from their firearms accessories. Proudly made in the USA, each magazine is backed by a lifetime guarantee against manufacturer's defects, ensuring that you invest in quality that stands the test of time.

This particular model fits AR-15 rifles chambered in 5.56mm or .223 Remington, offering versatility for various shooting activities. The body is constructed from DuPont Zytel-based polymer—a material renowned for its durability and resilience under demanding conditions.

What sets this magazine apart are its meticulously engineered components: over-molded stamped steel feed lips and a robust magazine catch ensure seamless feeding of ammunition with every shot. At the heart of this design lies ProMag's patented anti-tilt Roller follower, which works tirelessly to prevent jamming and misfeeds—common pitfalls that can undermine your shooting experience.

The spring inside is precision-wound using heat-treated chrome silicon wire, providing consistent pressure and longevity even after thousands of rounds fired. This attention to detail at each step—from assembly checks to double-checks—ensures unwavering quality across all units produced.

With a capacity of 30 rounds housed within its sleek black polymer exterior, this steel-lined magazine offers ample firepower while maintaining an easy-to-handle form factor suitable for both novice shooters and seasoned marksmen alike.
