First Thoughts on the ATI MAM2B30 Amend 2 Magazine 223 Rem/300 Blackout/ 5.56x45mm NATO AR-15 30rd Black Detachable – 223 Remington/5.56 NATO Caliber, Aftermarket Origin
The ATI MAM2B30 Amend 2 Magazine is a 30-round AR-15 magazine designed to reliably feed both .223 Remington/5.56 NATO and .300 Blackout ammunition. Marketed by American Tactical Imports (ATI) under the Amend 2 brand, this magazine aims to provide a cost-effective and dependable option for AR-15 owners. I’ve handled countless magazines over my career, and I’m always on the lookout for a durable, multi-caliber compatible option that won’t break the bank.
My search for a .300 Blackout magazine led me to the ATI MAM2B30. I needed a reliable magazine specifically for subsonic .300 Blackout rounds, since not all 5.56 magazines feed them consistently.
Upon receiving the ATI MAM2B30, I immediately appreciated its lightweight yet sturdy feel. The polymer construction seemed robust, and the textured grip offered a secure hold. Compared to standard GI aluminum magazines, this felt more substantial. I also considered Magpul PMAGs and Lancer L5 AWM magazines, but ultimately chose the ATI MAM2B30 for its dual-caliber compatibility and promising price point.
My initial impression was one of cautious optimism. While the price raised an eyebrow, the build quality seemed promising enough to warrant a thorough field test.
Real-World Testing: Putting ATI MAM2B30 Amend 2 Magazine 223 Rem/300 Blackout/ 5.56x45mm NATO AR-15 30rd Black Detachable – 223 Remington/5.56 NATO Caliber, Aftermarket Origin to the Test
First Use Experience
My initial testing took place at my local outdoor shooting range. I used two different AR-15 platforms: one chambered in 5.56 NATO and another in .300 Blackout.
I ran several drills in both platforms, focusing on rapid mag changes and various shooting positions. The ATI MAM2B30 performed flawlessly with both 5.56 NATO and .300 Blackout rounds, even when transitioning between the two calibers within the same range session. No jams or failures to feed occurred during the initial testing, which boosted my confidence.
Extended Use & Reliability
After several months of regular use, the ATI MAM2B30 magazines have continued to perform admirably. They’ve been subjected to dusty conditions during desert shooting sessions and exposed to moisture during rainy range days.
I have observed no significant signs of wear and tear, beyond minor cosmetic scratches. Cleaning is straightforward, requiring only a quick wipe-down with a cloth and occasional lubrication of the internal components. Compared to some of the cheaper polymer magazines I’ve tested in the past, the ATI MAM2B30 has proven to be significantly more reliable and durable.
