The ProMag RM30SL 30-round AR-15 magazine delivers reliable, affordable capacity for your 5.56x45mm NATO rifle without breaking the bank. Built from durable DuPont Zytel polymer with a steel-lined feed path, this magazine is engineered to handle the demands of the range, competition, or field. Whether you're stocking up for a day at the range or building a practical defensive battery, the RM30SL offers the round count and dependability competitive shooters and hunters expect—at a price that makes buying in quantity painless.
ProMag has been manufacturing magazines in the USA for decades, and the RM30SL reflects that manufacturing discipline. Each magazine undergoes precision assembly with heat-treated chrome silicon springs wound to exacting standards. The combination of reinforced polymer body and steel-lined internals is proven to stand up to repeated loading, chambering, and ejection cycles without degradation. This is a workhorse magazine designed to run, not collect dust in a range bag.
The 30-round capacity makes the RM30SL a practical choice for AR-15 owners who want to minimize reload frequency during extended shooting sessions. The proven polymer-and-steel construction balances weight savings with durability, so you're not carrying unnecessary bulk. ProMag backs every magazine with a lifetime manufacturer's warranty, reflecting confidence in the quality of their assembly process and material selection.
