Ruger 90229 Mark III 10rd Magazine 22 LR E-Nickel Steel

The Ruger 90229 Mark III magazine delivers reliable feeding and enhanced durability for extended shooting sessions. This factory-engineered 10-round magazine features E-Nickel steel construction that resists corrosion while maintaining consistent spring tension across thousands of cycles.

What Makes This Different

Factory Ruger magazines undergo rigorous quality control testing that aftermarket alternatives often skip. The E-Nickel coating provides superior corrosion resistance compared to standard blued steel magazines, extending service life in humid conditions. Internal geometry matches exact factory specifications for optimal cartridge presentation and feeding reliability.
