ProMag RUGA45 .223 Rem/5.56 30rd Black Steel/Polymer Mini-14 Magazine

The ProMag RUGA45 is a 30-round detachable magazine purpose-built for the Ruger Mini-14 rifle chambered in .223 Remington and compatible with 5.56x45mm NATO. Built around ProMag's hybrid steel/polymer design, this magazine pairs a heat-treated steel feed tower with a body molded from a proprietary DuPont Zytel-based polymer, giving Mini-14 owners a lightweight magazine that resists cracking, warping, and feed-lip deformation under sustained fire. The steel components wear a low-glare black oxide finish that blends with factory Mini-14 magazines.

Designed as a direct-replacement, high-round-count alternative to factory Mini-14 magazines, the RUGA45 installs without modification and feeds reliably from the Mini-14's signature fixed-position magazine well. The 30-round capacity gives ranch-rifle, tactical, and sporting Mini-14 users a familiar round count for range sessions, training drills, and defensive applications, while the polymer body keeps loaded weight manageable compared to all-steel designs. Steel internal surfaces at the feed lips and locking points ensure consistent presentation round after round, and the hybrid construction makes it a smart spare or backup to keep loaded alongside factory magazines.
