Overview: What the CMMG AR-15 magazine brings to the table
The CMMG AR-15 is a 10 round AR patterned magazine designed specifically to run .350 Legend ammunition in a standard AR-15 magazine well. What matters most here is that it enables shooters to use straight-walled .350 Legend rounds without modifying the lower receiver. At a retail price of $21.59, this magazine is an economical way to add new capability to an existing AR platform.
Design & compatibility
AR-pattern fit and construction
Built to AR-pattern dimensions, the CMMG AR-15 drops into a standard AR-15 magwell and locks up like any other AR magazine. The 10-round capacity meets many state regulations for hunting and provides a compact, mission-focused loadout for defense scenarios. The design intent is simple: change caliber without changing platforms.
Why .350 Legend in an AR-15?
.350 Legend is a straight-walled cartridge that was designed to offer effective terminal performance on game and strong stopping power in compact, controllable recoil packages. In an AR-15 platform, it gives users a balance between manageable recoil and significant bullet mass. For folks operating where straight-walled cartridges are preferred or required, this magazine provides plug-and-play access to that option.
Ballistics and practical performance of .350 Legend
.350 Legend performs best in short- to medium-range applications. It carries heavier frontal area and energy than many pistol calibers while remaining tame in recoil compared to magnum rifle rounds. That makes it a sensible choice for close-range defense, woods hunting, and utility roles where over-penetration and excessive recoil are concerns. When paired with a purpose-built magazine like the CMMG AR-15, you get reliable feeding and the ergonomics of a familiar AR pattern.
Field reliability and handling
Functionality in the field comes down to tolerances, follower design, and materials. The CMMG AR-15 follows AR-pattern geometry closely, which reduces the chance of fitment surprises between lowers. The 10-round capacity is a deliberate choice for users who need compliance with hunting laws or prefer a compact magazine profile for tactical applications. Treat it like any magazine: keep it clean, inspect the feed lips and spring periodically, and use quality ammunition for best results.
Loading and carrying tips
Load evenly and avoid over-compressing the spring. Carry magazines in dedicated pouches designed for AR mags to protect feed lips and maintain consistent orientation. For storage, a light coat of protective oil on the exterior surfaces and a dry interior keeps corrosion at bay without affecting feeding reliability.

Applications: defense, range, and hunting
For tactical defense, the CMMG AR-15 magazine loaded with .350 Legend offers a blend of controllability and terminal performance suitable for home defense or vehicle carry where AR ergonomics are preferred. For hunters operating under straight-wall cartridge laws, it’s a direct route to compliance while retaining the handling characteristics you expect from an AR platform. Range usage is straightforward — it’s also a good platform for training with heavier-bullet calibers without stepping up to larger rifles.
Why the brand matters
Cmmg has built a reputation for practical innovation around the AR platform. While we reference the brand to give context, the focus here is the solution: a magazine that permits .350 Legend in a standard lower. That capability is notable because it minimizes the barrier to entry for users who want to experiment with or adopt .350 Legend without swapping receivers or doing complex conversions.
Maintenance, spare parts, and common issues
Standard magazine maintenance applies. Replace a damaged spring or follower as needed. Verify feed lips are not bent and keep ammunition clean. If you experience any feed issues, isolate ammunition lots and test with factory-loaded .350 Legend rounds. Magazine hygiene and periodic inspection prevent most common hiccups in the field.
Purchasing considerations
At $21.59, the CMMG AR-15 magazine is competitively priced for users looking to outfit an AR with .350 Legend capability. Because it’s an AR-pattern magazine, compatibility with standard pouches and carriers is immediate. When you click through to the product page you’ll see the purchase flow that takes you to the retailer for final checkout — a straightforward way to add this capability to your kit quickly.
We recommend pairing two magazines per rifle for training, and adding another for a ready/staged setup at home. Keep one magazine loaded for immediate access and rotate stored magazines periodically to maintain spring life.
We write from experience: choose gear that respects the platform and accomplishes the mission. The CMMG AR-15 magazine gives shooters a clean, economical way to run .350 Legend through a standard AR15 magwell with predictable handling and serviceable price. If you’re evaluating straight-walled options or want reliable feeding for .350 Legend in an AR-pattern rifle, this mag is worth a close look.
