CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin Review

The CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin Made a Bold First Impression

The CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin represents an attempt to efficiently feed the increasingly popular 350 Legend cartridge in the AR-15 platform, albeit with a capacity restriction. This magazine promises reliable feeding of the straight-walled cartridge for hunting or range use, all while adhering to capacity restrictions where necessary. As an experienced outdoorsman and tactical gear specialist, I was eager to see if this magazine could stand up to the rigors of the field.

I sought out this magazine because I needed a compliant option for hunting in states with capacity restrictions on straight-walled cartridges. The 350 Legend has proven itself to be a capable deer cartridge, and I wanted to utilize my existing AR-15 platform. Unboxing the CMMG magazine, I immediately noted its robust construction and standard AR-15 magazine dimensions. The black finish appeared durable, and the magazine felt solid in hand, instilling initial confidence.

Compared to a standard 30-round 5.56 magazine, the CMMG magazine felt more substantial, likely due to the modified internals required to properly feed the larger 350 Legend rounds. I had considered other 5-round 350 Legend magazines from various brands, but ultimately chose the CMMG offering based on CMMG‘s reputation for quality AR components and generally positive user reviews. My first impression was cautiously optimistic; however, the true test would be on the range and in the field.

Real-World Testing: Putting CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin to the Test

First Use Experience

I tested the CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin at my local outdoor shooting range. The weather was dry and sunny, offering ideal conditions for testing. My primary focus was on reliable feeding and smooth cycling of the 350 Legend cartridge. I immediately encountered issues.

The rifle consistently failed to cycle correctly with this magazine. It experienced failures to feed and stove-pipes frequently. This was unexpected, and frustrating.

Extended Use & Reliability

After several range trips and numerous attempts to diagnose the cycling issue, the CMMG magazine continued to perform unreliably. The durability of the magazine itself seemed adequate. There were no visible signs of wear or damage. Cleaning and maintenance were straightforward, identical to any other AR-15 magazine.

However, the consistent cycling issues made it impossible to recommend this magazine based on my experience. This was a significant disappointment, especially compared to my positive experiences with other CMMG products and other brands of 350 Legend magazines. Another brand of 350 Legend magazine, when tested in the same rifle, worked flawlessly.

Breaking Down the Features of CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin

Specifications

The CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin is designed specifically for the AR-15 platform. It is chambered in 350 Legend, with a 5-round capacity. The magazine is manufactured by CMMG and is of OEM origin.

The magazine body is constructed from a durable black polymer, similar to standard AR-15 magazines. The 5-round capacity is a key specification for compliance in states with hunting restrictions. This limited capacity affects the overall utility of the magazine, primarily restricting it to hunting or range use where capacity is limited.

Performance & Functionality

Unfortunately, in my testing, the CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin fell short in terms of performance. The consistent cycling failures severely hampered its functionality. The magazine failed to reliably feed the 350 Legend cartridge, resulting in frequent malfunctions.

This unreliability is a major weakness, overshadowing any potential strengths. The magazine did not meet my expectations for reliable feeding, a critical function for any firearm magazine.

Design & Ergonomics

The design of the CMMG magazine is essentially a modified AR-15 magazine. It fits seamlessly into any standard AR-15 magazine well. The black polymer construction feels robust and well-made.

However, ergonomic considerations are secondary to reliable function. The magazine’s unreliable feeding negates any potential ergonomic benefits.

Durability & Maintenance

The CMMG magazine appears to be durable. It withstood multiple range trips and manipulations without showing signs of wear or damage. Maintenance is simple, involving basic cleaning similar to any other AR-15 magazine.

However, durability and ease of maintenance are irrelevant if the magazine fails to function reliably.

Accessories and Customization Options

The CMMG AR-15 350 Legend AR-15 5rd Black Detachable – 350 Legend Caliber, OEM Origin is a self-contained unit. There are no specific accessories or customization options directly related to the magazine itself. Compatibility with the AR-15 platform means it can be used with various AR-15 accessories, such as magazine pouches.

However, given its unreliable performance, adding accessories would be futile.
