Description
This is a straightforward, purpose-built magazine for .350 Legend AR-15 builds. It holds 10 rounds and was engineered specifically for the straight-walled .350 Legend cartridge, which requires its own magazine design but works with standard AR-15 lower receivers fitted with a .350 barrel.
Built to Last With Stainless Steel Construction
The magazine body is made from stainless steel with a black finish, so it resists corrosion and won't swell in heat or crack in cold weather like polymer magazines can. The precision-machined stainless steel body ensures a snug fit in your magazine well every time. If you keep mags loaded for extended periods without shooting them, stainless steel gives you peace of mind that the magazine will perform when you need it.
Anti-Tilt Follower Keeps Rounds Feeding Smoothly
The anti-tilt follower is a simple feature with real benefits. It keeps each round properly aligned as it moves up the magazine stack, which prevents feeding issues and malfunctions. Combined with a quality spring, this means consistent, reliable feeding from full to empty. Reviewers across multiple retailers report no feeding problems and praise the overall construction quality of these mags.
Compact Size Perfect for Hunting
At 10 rounds, this magazine works well for hunting situations where a lower profile is an advantage. It barely protrudes below the magazine well, making it convenient to carry in a scabbard, ground blind, or while moving on foot. The compact size also makes quick mag changes easier compared to larger capacity magazines.

Frequently Asked Questions
Will this magazine work with other manufacturers' .350 Legend barrels?
The CMMG magazine is engineered for CMMG .350 Legend barrels and systems. Due to design variations between manufacturers on barrel extensions and feed ramps, this magazine may require modification to function with other brands' .350 Legend barrels. Check compatibility with your specific upper before purchase.
Can I use this magazine with standard .223/5.56 ammunition?
No, this magazine is designed exclusively for .350 Legend ammunition. The .350 Legend requires a proprietary magazine, so this won't work with .223 or 5.56 ammo.
What does the anti-tilt follower do?
The anti-tilt follower keeps each round properly aligned as it feeds up the magazine stack. This helps prevent feeding malfunctions and ensures consistent, reliable ammunition feeding from a full magazine down to the last round.
Is the stainless steel body safe for long-term loaded storage?
Yes, stainless steel won't swell or degrade from extended storage like some polymer magazines can. You can safely keep this magazine loaded without worry that the metal will flex or warp over time.
