The ProMag RUGA4FDE is a polymer-bodied 30-round magazine designed to feed .223 Remington and 5.56 NATO ammunition through Ruger Mini-14 rifles. Built with a proprietary Dupont Zytel polymer construction, this magazine weighs less than traditional steel or aluminum options while maintaining durability through everyday handling and range use.
Internally, the magazine features heat-treated chrome silicon wire springs precision-wound to specification and an injection-molded follower. Every step of assembly is checked and double-checked during manufacturing to maintain consistent quality. The flat dark earth color provides a practical finish that resists dust and shows wear less noticeably than lighter colors. The flat bottom baseplate design allows for stable magazine changes on a shooting bench or table.
Mini-14 rifles have specific dimensional requirements for feed lips and follower geometry due to their rotating bolt system. Because of these tolerances, some users report tighter initial fit or slight adjustment may be needed when first installing aftermarket magazines. The polymer construction in this ProMag keeps weight down compared to steel alternatives, which matters when running multiple magazines in the field or at the range.
ProMag magazines are made in the USA and come backed by a lifetime guarantee against manufacturer defects, which provides peace of mind on your purchase. With a 30-round capacity, this magazine works with standard .223 / 5.56 ammunition and fits all Ruger Mini-14 models except the Mini-30 (which uses a different magazine platform).
This ProMag magazine is designed for all standard Ruger Mini-14 rifles chambered in .223 Remington or 5.56 NATO. It will not work with the Mini-30, which uses a different magazine platform. Fit and function can vary slightly due to manufacturing tolerances, so some users report their magazines may need a few rounds through them to function optimally.
ProMag's Dupont Zytel polymer offers weight savings compared to steel or aluminum alternatives, which can be beneficial when carrying multiple magazines. The polymer is durable for standard handling and range use. Some users prefer the durability and longevity track record of factory Ruger steel magazines for critical use applications.
ProMag backs these magazines with a lifetime warranty against manufacturer defects in materials and workmanship. This covers defects that arise from normal use and manufacturing issues, not damage from abuse, modification, or normal wear.
Yes, this magazine is compatible with both .223 Remington and 5.56 NATO ammunition, as they share the same external dimensions. The magazine itself doesn't change based on which ammunition you're loading, though some shooters prefer to keep magazines segregated by cartridge type for consistency.
