AR-15 and AK Dust test

The Cav Arms guys did an extreme dust test on an AR-15. Turns out AR-15 cannot handle being buried in sand and then run over by a Jeep … who knew? Apart from the “Jeep test”, it did really well.

They also tested an AK derivative, a 5.56mm SAR-3, which did not do as well. It seems odd that the trigger group would fail to function. I have posted videos on the blog showing AKs working under worse conditions.

    Not to be a jerk, but why would you us a 5.56 AK for this test? They are known to be less reliable. Would this have prevented the failures? Probably not, but still.

    These tests are bogus, unless they repeated it over one hundred times, it's not scientific in the least.

    Also the only way that could ever happen is if you dropped your rifle (your's supposed to be wearing a sling) and covered it with sand. (A specific as yet unknown type of sand, I might add)

    The only way to really perform a dust and dirt test is to construct a chamber that continually simulates blowing dust around, (as in realistic desert conditions) leave the rifle in there for around 10 hours and see if it works. The 'dust' can would be artificially made of different fineness of grains, with a specific ration. All the specs and materials should be easily available, not expensive and posted on the Internet, and then people would actually be able to replicate the test and see if it holds up. Not only would that be somewhat realistic, but it actually approaches the level of a scientific test, instead of this crappy promotional video.

    I can't wait until mythbusters tackles this.
