This ProMag polymer magazine gives you extra capacity without extra weight. The RUGA11 holds 20 rounds of .223 Remington or 5.56 NATO ammunition and uses injection-molded DuPont Zytel polymer for the body and followers, which resists impact and corrosion better than cheaper plastics. The heat-treated chrome-silicon wire spring maintains tension even after extended storage, so you don't have to worry about a mag that's been sitting loaded for months suddenly failing when you need it.
The magazine construction is straightforward but effective. The curved polymer body follows the natural shape of bottlenecked .223 cartridges, and the black finish blends with most Mini-14 setups. The follower is molded from the same polymer compound as the magazine body, which reduces friction during feeding cycles. ProMag backs every magazine they make with a lifetime warranty against manufacturer defects, so if something goes wrong with materials or workmanship, you're covered.
This magazine is designed for Ruger Mini-14 rifles chambered in .223/5.56. It fits best in pre-580 series models, where users report consistent feeding with both surplus and commercial ammunition. If you own a newer 580-series Mini-14, test this magazine thoroughly at the range before relying on it for anything critical, as some 580-series owners have experienced fitment issues where the magazine sits slightly lower in the mag well, potentially affecting feeding reliability.
With 20 rounds, you get a meaningful capacity increase over standard 5 or 10-round factory mags without the bulk of 30-round magazines. The lighter polymer construction keeps your rifle balanced during extended shooting sessions, and the magazine is easy to pack and store. Made in the USA.
The RUGA11 performs best in pre-580 series Mini-14s. Some owners with 580-series models have reported fitment issues where the magazine sits lower in the mag well, potentially affecting feeding. Test this magazine thoroughly at the range before relying on it for anything critical. If you experience feeding problems, contact ProMag to explore replacement options under their lifetime warranty.
ProMag's heat-treated chrome-silicon springs are designed to maintain tension even after being loaded and stored for extended periods. The polymer body resists degradation from sunlight and temperature swings, so you can keep a loaded magazine in your range bag or truck without worrying about spring fatigue.
DuPont Zytel polymer is engineered to resist impact and corrosion better than basic plastics, and it weighs less than steel for the same capacity. For range use and hunting, polymer magazines are plenty durable. The trade-off is that polymer can wear or crack if mistreated, whereas steel can usually withstand more abuse. ProMag backs both with a lifetime warranty.
The magazine comes as-is with no additional accessories. It's ready to load and use right out of the box. For best performance, keep the follower and spring area clean and dry, and avoid dropping the magazine repeatedly on hard surfaces.
