Originally developed for the U.S. military in the early 1970s, the 30-round AR-15-style magazine has become a staple in the firearm industry. Sold under the SureFeed brand, magazines manufactured by Okay Industries co-developed what would become the standard capacity magazine for the AR-15. For the first time, these magazines are available for sale to the civilian consumer.
SureFeed magazines are 100-percent American-made, and all components meet or exceed Mil-Spec. Bodies and floor plates are lightweight aluminum, heat-treated to Mil-Spec requirements for strength and durability, then hard-coat anodized and finished in either a Mil-Spec dry-film-lube grey or tactical-Black PTFE. A four-way, anti-tilt, self-lubricating, non-hygroscopic resin follower and stainless steel spring foster proper alignment for positive performance.
