What magazines does .338 ARC use?

.338 ARC is designed for the AR-15 platform and uses magazines compatible with its cartridge geometry rather than a standard 5.56-only magazine specification. Magazine capacity and compatibility can vary by manufacturer and configuration, so select a magazine specifically listed by its manufacturer as compatible with .338 ARC. Always verify the magazine specifications for the particular firearm and ammunition being used.
