The Ruger 90679 AR-556 5-round magazine for .450 Bushmaster is a purpose-built magazine designed specifically for the Ruger AR-556 platform in this hard-hitting cartridge. Built from .020 gauge 410 stainless steel and heat-treated for strength, this magazine delivers the durability hunters and shooters demand from a centerfire rifle magazine. Whether you're working up handloads or running factory ammunition, this 5-round capacity keeps you in the field longer and at the ready.
Construction matters in harsh field conditions. The magazine is chemically treated for corrosion resistance and finished with Ruger's proprietary Marlube coating—a finish that hardens into the surface rather than wearing away, while providing self-lubricating properties to keep things running smooth. The chrome silicon spring is paired with an enhanced anti-tilt black polymer follower that ensures reliable feeding and seating with each cycle, eliminating the feeding hiccups that can derail a hunt or range session.
Interior dimensions are precisely engineered at 2.316 inches OAL (with tolerances of +/- .002 inch), giving you a magazine that reliably accommodates both fresh factory rounds and reloads. If you're running a Ruger AR-556 in .450 Bushmaster and want a spare magazine you can trust in the field or at the range, this factory Ruger magazine is the straightforward choice.
