The DuraMag Ruger American AR Pattern Rifle Magazine 400 Legend 4/Rd is a flush-fit steel magazine engineered specifically for Ruger American AR Pattern rifles that use AR-15/STANAG-style magazines. Designed around the 400 Legend cartridge, it maintains the rifle’s slim profile while delivering smooth, dependable feeding shot after shot.

This 4-round Duramag SS Flush-Fit magazine is ideal when you prefer a compact, unobtrusive setup for hunting or bench work instead of higher-capacity magazines. It works with both Gen 1 and Gen 2 Ruger American rifles that retain the OEM stock and mag-well for AR pattern magazines, giving you a low-profile, comfortable carry and handling experience backed by DuraMag’s focus on reliability and smart design.
