Arcturus EMM AR MOD1 M4/M16 30/130 Round Rifle Magazine Review

Is the Arcturus Variable-Cap Windowed EMM AR MOD1, M4/M16, 30/130 Rounds, Rifle Magazine All Talk?

The Arcturus Variable-Cap Windowed EMM AR MOD1, M4/M16, 30/130 Rounds, Rifle Magazine aims to offer versatility with its adjustable capacity, bridging the gap between standard-capacity and higher-capacity magazines. Arcturus promises a robust polymer construction and convenient features like a capacity window. Does this magazine live up to the hype or fall short in real-world scenarios?

I was searching for a magazine that could easily adapt to different scenarios – from training exercises requiring realistic round counts to situations where a higher capacity is advantageous. Standard 30-round magazines are my go-to, but the allure of quickly switching to a higher capacity without needing a separate magazine pouch was enticing. This magazine seemed to offer the best of both worlds.

Upon unboxing, the magazine felt solid and well-built. The polymer felt durable, and the window provided a clear view of the remaining rounds. The adjustable capacity mechanism seemed simple enough to operate, but I reserved judgment until I could test it at the range.

I considered magazines from Magpul and Lancer, known for their reliability. However, the Arcturus magazine’s variable capacity feature set it apart. I was intrigued by the potential to streamline my loadout. My initial excitement was tempered by the expectation that a variable-capacity magazine might compromise reliability compared to a fixed-capacity one.

Real-World Testing: Putting Arcturus Variable-Cap Windowed EMM AR MOD1, M4/M16, 30/130 Rounds, Rifle Magazine to the Test

First Use Experience

I tested the Arcturus Variable-Cap Windowed EMM AR MOD1, M4/M16, 30/130 Rounds, Rifle Magazine at an outdoor shooting range, running it through my standard M4-style AR-15. Conditions were typical for a late summer day – sunny, with a slight breeze and temperatures in the mid-70s. I loaded it with both .223 Remington and 5.56 NATO ammunition to test its versatility.

The magazine performed well in both 30-round and 130-round configurations during the initial testing. Switching between capacities was surprisingly easy, requiring only a few seconds. There were no noticeable feeding issues or malfunctions during the first few hundred rounds.

The Arcturus magazine locked into the magwell smoothly, and the rounds fed reliably without any hiccups. I did notice that the magazine was slightly heavier than my standard magazines, especially when fully loaded in the 130-round configuration. This required some adjustment in handling.

Extended Use & Reliability

After several weeks of regular use, the Arcturus Variable-Cap Windowed EMM AR MOD1, M4/M16, 30/130 Rounds, Rifle Magazine has held up surprisingly well. I’ve put approximately 1,500 rounds through it, and it continues to function reliably. There are some minor scuff marks on the polymer body, but nothing significant.

I’ve also used it in a couple of outdoor training sessions where it encountered rain and some dust. It continued to feed reliably without any cleaning or maintenance during those sessions. Cleaning is simple.

Compared to some cheaper magazines I’ve used in the past, the Arcturus magazine feels significantly more robust. While it might not outperform premium magazines like those from Magpul in terms of weight, the variable capacity feature gives it a distinct advantage. Overall, I am impressed.
