AR-15 MAGAZINE TEST: CRUSH TESTING

There are several things to consider during crush testing. First, crushing the magazines does not always lead to failure. For example, in stage one of our crush testing, we look at how the magazine performs before and after 1K Lbs of pressure is applied. In our test group, only one magazine failed before reaching 1K Lbs of pressure. These failures generally occur when the magazine is pushed past its load limit to its breaking point. For polymer magazines, this often means pushing them to the point that the outer shell collapses. For metal magazines, the breaking point is often the welds or seams. Take a look at our AR-15 magazine test results in the video above.

FINAL THOUGHTS

AR-15 magazine test
Feel free to share our AR-15 magazine test data with other gun owners.

There’s a lot of data to unpack in our AR-15 magazine test. In summary, almost all of the magazines we tested seated well in our Colt test rifle and cycled 90-rounds of ammo under normal conditions without issue. We feel confident that any of the magazines in our test would be good options for use at indoor or outdoor gun ranges. However, not all of the magazines in our test were capable of handling basic gun training scenarios. Even fewer were up for the task of handling environmental situations and advanced gun training scenarios.

During environmental water testing, all candidates in our AR-15 magazine test performed above average. No magazines had issues with retaining water or being unable to drain it quickly enough to cycle correctly. We did however find some corrosion and rust spots on the steel magazines a few days after they dried out. Aluminum and steel magazines were largely unaffected by sand and soil, passing our environmental testing without issue. Polymer magazines did not perform well with sand, however, many performed well with soil.

At least two polymer magazines failed our drop test, both developing cracks in roughly the same area near the rear spine. It’s possible that both of these magazines were not manufactured to the correct specifications, resulting in sample variation, which led to the failure. Aluminum magazines held up well to drop testing, however, it should be noted that all metals can dent, bend, or deform when dropped repeatedly. Feed lips were the Achilles heel of steel magazines. They all bent inward a certain degree when dropped and had to be reshaped using a multi-tool to continue testing.

Testing, Training, Repetition

As always, be sure to test your gear for compatibility before taking it out into the real world. Certain gear combinations will work better together than others. If you’re going to have a malfunction or compatibility issue, it’s better to work through it at the gun range, rather than in a critical situation where failure isn’t an option. Train with your gear the way you intend to use it. We recommend taking classes from certified instructors who are well respected in the gun community.
