A Dependable Metal Magazine Made Specifically For .350 Legend

Built specifically for the hard-hitting .350 Legend cartridge, the CMMG 20-Round Magazine gives your AR-15 the feeding reliability and rugged construction you need for outdoor hunting adventures. Designed to fit any mil-spec AR-15 lower, this mag is optimized for the unique dimensions of .350 Legend ammo, ensuring proper stacking and consistent feeding. The durable steel body is built to take abuse in the field, while the anti-tilt follower and reliable spring tension keep your rounds feeding smoothly.

Features

  • Holds 20 rounds of .350 Legend ammo
  • Compatible with mil-spec AR-15 lowers and .350 Legend Uppers
  • The new generation has specially engineered internal geometry and improved feed lips for reliable feeding
  • Durable polymer construction built to withstand hard use
  • Lightweight, easy to load, and simple to clean (looking at you P90 magazines)

NOTE: Due to design variations between manufacturers on the barrel extension/feed ramp of the 350 Legend barrel, this magazine may not function with any other manufacturers’ barrels without the necessity of modification to the magazine, depending on the manufacturer specs on the barrel.
