The CMMG 35AFC66 magazine delivers reliable feeding for 350 Legend AR-15 builds with enhanced durability over standard aluminum alternatives. This 20-round magazine features stainless steel construction that resists corrosion and maintains dimensional stability under heavy use.

What Makes This Different

Stainless steel construction sets this magazine apart from typical aluminum AR magazines, offering superior resistance to dents, corrosion, and wear. The 35AFC66 incorporates CMMG's proven follower design optimized specifically for the 350 Legend cartridge geometry. Feed lips maintain proper tension longer than aluminum counterparts, reducing the risk of double-feeds or failure-to-feed malfunctions that can occur with worn magazines.

Key Features

  • 20-round capacity optimized for 350 Legend cartridge dimensions
  • Stainless steel body construction for enhanced durability and corrosion resistance
  • Anti-tilt follower design prevents binding and ensures consistent feeding
  • Standard STANAG pattern fits all mil-spec AR-15 lower receivers
  • Black finish reduces glare and maintains professional appearance
  • Reinforced feed lips maintain proper cartridge presentation angle
  • Compatible with standard AR-15 magazine pouches and carriers
Field performance demonstrates consistent feeding across temperature ranges from -20°F to 140°F without binding or extraction issues. The stainless steel construction maintains feed lip geometry even after thousands of loading cycles, making it suitable for competitive shooting, hunting applications, and duty use. The 350 Legend cartridge's straight-wall design benefits from the magazine's optimized internal dimensions that prevent cartridge setback during rapid fire sequences.
