A lot of people on the internet have this idea in their heads that AR15s are these finicky, maintenance queens that need to be constantly cleaned and scraped free of any bit of debris lest they suffer a catastrophic malfunction. There are lot of reasons why people think this, but suffice to say it’s not true. Our buddy John from Ballistic Radio, with the help of Knight’s Armament and Freedom Munitions decided to show you how not true that was, so he shot 15,000 rounds through an AR15 without cleaning it, then dumped an entire bag of sand on it. (some NSFW language, so use your headphones)
Now, I know EXACTLY what the smacktards are going to say: “Caleb, he had the dust cover closed! That keeps anything from getting in the action!” Of course he had the dust cover closed, that’s what it is there for. But hey, he filmed another video after that to show you how much stuff the dust cover actually lets get in the gun. Trigger warning for godawful screeching bolt noises.
As you can see, there is a ton of grit and junk in that gun…but it keeps on working. Just going and going and going. John’s made sure to keep the gun lubricated, which is really all you need to do with an AR15. Keep it wet and it’ll keep running.
Of course, there are going to be people who say that this test doesn’t count and he should lock the bolt to the rear and pour sand directly into the action. What exactly field conditions is that going to replicate? Are people using their AR ejection ports as shovels? I don’t think so. The people that are calling for that kind of abuse aren’t interested in a fair test, they’re 1) idiots, and 2) just interested making the rifle fail. Why would they want it to fail? Because they’re mentally invested in the (incorrect) idea that the AR15 is a delicate f***ing flower that needs to be constantly babied and meticulously cleaned. It doesn’t. It’s a tough implement of war that’s served our country for nearly 50 years.
In fact, it’s probably more reliable than an AK47.
