Truly a modern classic of a rifle, designed with the simple and efficient ingenuity to utilize commonly available AR-15 / STANAG pattern magazines for common intermediate calibers, thus increasing it's overall effectiveness and keeping costs low.
When you don't need capacity though and prioritize ergonomics and comfort, the Duramag SS Flush-Fit magazines are a perfect solution for both your Gen 1 and Gen 2 Ruger American rifles with the OEM stock / mag-well for AR pattern magazines.
I just got this and it chambers okay so far,won’t really know till I shoot the gun. Too bad my magazine that came with the ruger was a sloppy fit causing problems for my gun. I bought this to replace the dura - mag for my Ruger 400 legend,the original magazine was a poor fit,poorly made too bad dura-mag wasn’t offering this when I got my gun.

Ruger American 400 legend flush fit magazine
Posted by Chris Caldwell on 24th Nov 2025
Just received mine in the mail. Tried it out in my rifle and it works awesome! Y’all knocked it outta the park with this one! It makes the rifle so much easier to carry now without the big bulky magazine sticking out of the bottom. Just in time for gun season. Thanks!

Saved me from wanting to buy a whole new stock or chassis! Makes the gun so much more functional for carrying and hunting!

.400 Legend

Only .400 Legend flush fit magazine on the market. Used today on my first hunt with it and couldn’t be happier. Helps make the rifle much sleeker and easier to manage. Feeds just as the factory magazine does (also made by DuraMag).

fits and functions great. did not like the clunky factory AR style mag. This mag is much smoother looking. Glad I purchased it.

350 Legend Ruger American AR Pattern Flush-Fit Mag
Posted by Terry S. on 20th Nov 2025
Perfect fit for my 350 Ruger American Gen II rifle. Had no trouble fitting 5 rounds in the mag and cycles even better than the AR mag that comes with the rifle.
