ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model Review

First Thoughts on the ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model

The AR-15 platform is known for its modularity and adaptability, but chambering it in 7.62x39mm brings a whole new level of versatility. The ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model promises to deliver reliable feeding for this popular AK-47 round in the AR-15. With its blued steel construction and 30-round capacity, this magazine aims to offer a durable and high-capacity solution for AR-15 enthusiasts looking to shoot the readily available and affordable 7.62x39mm cartridge.

My interest in this magazine stemmed from a desire to expand the capabilities of my existing AR-15. I wanted a cost-effective way to shoot 7.62x39mm without dedicating myself to an entirely separate AK platform. The ProMag magazine seemed like a promising solution, but the reputation of aftermarket magazines for non-standard AR calibers often precedes them, and not always in a good way.

Upon receiving the ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model, my initial impression was that it felt robust. The blued steel construction gave it a substantial weight, and the finish appeared even. Compared to some polymer magazines I’ve used, this one felt like it could take a beating, but only live testing would tell for sure.

I considered other 7.62×39 AR magazines from brands like C Products Defense, but the ProMag offered a more attractive price point. I figured it was worth a shot, even with the mixed reviews I’d seen online. My first impression was cautiously optimistic; I was eager to see if it would live up to the hype or become another unreliable addition to my range bag.

Real-World Testing: Putting ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model to the Test

First Use Experience

I tested the ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model at my local outdoor shooting range. The weather was dry and sunny, ideal conditions for testing magazine functionality. I ran about 150 rounds of various 7.62x39mm ammunition, including steel-cased Russian surplus and some brass-cased commercial loads.

Initially, the magazine presented some feeding issues with the steel-cased ammo. The first few rounds seemed to hang up, requiring a firm tap on the bottom of the magazine to seat correctly. After those initial hiccups, the magazine fed more reliably, but I still experienced a few failures to feed, particularly with the steel-cased rounds.

Extended Use & Reliability

After several range trips and approximately 500 rounds through the ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model, its performance remained inconsistent. While it performed acceptably with brass-cased ammunition, the steel-cased rounds continued to cause occasional feeding problems. I also noticed that the blued steel finish began to show wear, particularly around the feed lips and magazine catch area.

Cleaning the magazine was relatively straightforward; I disassembled it and cleaned the interior with a brush and solvent. The chrome-silicon wire spring appeared to hold its tension well, even after repeated use. Compared to my experience with other AR-15 magazines in 5.56, the ProMag required more frequent cleaning to maintain acceptable functionality, especially when using steel-cased ammunition. Ultimately, the magazine’s reliability was a disappointment compared to the consistent performance I’ve come to expect from standard AR-15 magazines.

Specifications

The ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model boasts the following specifications:

• Caliber: 7.62 x 39mm. This is a crucial detail, making it compatible with AR-15 rifles chambered in this specific caliber, providing an alternative to the standard 5.56 NATO.
• Capacity: 30 Rounds. This high capacity allows for extended shooting sessions without frequent reloading, offering a distinct advantage in both recreational and tactical scenarios.
• Finish: Blued Steel. The blued steel finish provides a level of corrosion resistance and durability, designed to withstand the rigors of regular use and harsh environments.
• Model: AR-15. Specifically designed for AR-15 platforms, ensuring compatibility with standard AR-15 magazine wells (though some fitting may be required).
• Origin: Aftermarket. As an aftermarket magazine, it’s manufactured independently of the original firearm manufacturer, Colt, offering a potentially more affordable option.

These specifications are critical because they dictate the magazine’s compatibility, capacity, and durability. The 7.62x39mm caliber dictates the ammunition it can use, while the 30-round capacity provides ample firepower. The blued steel construction is essential for longevity, particularly with the potentially corrosive nature of some surplus ammunition.

Performance & Functionality

The ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model aims to provide reliable feeding of 7.62x39mm rounds in an AR-15 platform. However, in practice, its performance can be inconsistent.

Its primary strength is its high capacity, allowing for more extended shooting sessions between reloads. The blued steel construction provides a robust feel.

However, the magazine’s main weakness is its reliability, particularly with steel-cased ammunition. Feeding issues and failures to feed are not uncommon, which can be frustrating and reduce confidence in its performance.

Overall, the magazine’s performance is below expectations, especially when compared to the reliability of standard 5.56 AR-15 magazines. While it functions adequately with brass-cased ammunition, its unreliability with steel-cased rounds makes it a less desirable option.

Design & Ergonomics

The ProMag COLA-20 AR-15 Magazine 30RD 7.62x39mm Blued Steel – 7.62 x 39mm Caliber, 30 Rounds, Aftermarket Origin, AR-15 Model features a standard AR-15 magazine design with a blued steel body. The magazine’s construction feels solid and durable.

The magazine fits securely into standard AR-15 magazine wells designed for 7.62x39mm conversions. However, some users have reported needing to adjust the magazine catch for optimal fit.

Durability & Maintenance

With proper care, the magazine should last for a reasonable amount of time. However, the steel-cased ammunition can accelerate wear due to its harder composition and potential for increased friction.

Disassembling the magazine for cleaning and maintenance is straightforward. Regular cleaning is recommended to prevent malfunctions, especially after using steel-cased ammunition.
