Description
If you're running a .350 Legend build, you need a magazine designed for it. Standard AR-15 magazines simply won't feed the larger cartridge reliably, but the CMMG 5-round magazine is engineered specifically for this straight-walled hunting round.
What Makes This CMMG Magazine Necessary
The .350 Legend is fatter than 5.56 NATO, and that diameter difference creates feeding issues with generic AR mags. This CMMG magazine features optimized feed lips and internal geometry that accommodate the wider case profile. You get the right feed angle every time, which matters when you're in the field.
Built from Stainless Steel with Real Durability
The body is 410 stainless steel with a hard black finish that resists scratches and corrosion. The anti-tilt follower keeps rounds sitting at the correct angle for smooth feeding and prevents the binding that plagued earlier .350 magazine designs. It's all metal construction except the follower, which means no cheap plastic that flexes or swells from extended storage or temperature changes.
A Five-Round Mag That Just Works
The compact five-round capacity makes this ideal for hunting applications where portability and compliance matter. The magazine ejects cleanly, loads easily, and feeds without hiccups. Users consistently report flawless function once they have the right mag, and that reliability difference between purpose-built magazines and improvised solutions is night and day.

Frequently Asked Questions
Can I use a standard AR-15 magazine for .350 Legend?
No. Standard 5.56 NATO magazines won't feed .350 Legend reliably because the larger cartridge diameter doesn't align with the magazine's internal geometry. You need a magazine specifically designed for .350 Legend, like this CMMG model, to ensure consistent feeding and avoid jams.
Is the anti-tilt follower important?
Yes. The anti-tilt design keeps rounds positioned at the correct feeding angle, preventing binding and jams. This is especially critical for .350 Legend where the larger cartridge demands precise alignment throughout the feeding cycle.
Will this magazine work with other .350 Legend rifles?
This magazine is designed for AR-15 platform rifles chambered in .350 Legend. Some compatibility variations exist between manufacturers due to barrel extension and feed ramp differences, so verify fitment with your specific rifle.
Is stainless steel better than polymer for storage?
For extended storage while loaded, stainless steel is superior. It won't flex or swell from temperature changes or sitting loaded, unlike polymer. The hard black finish also protects against corrosion if stored in varying conditions.
