Ballistic Radio has been diligently doing what most of us could not – torture testing an AR-15 through the end of its life. Now past 15,000 rounds of cleaning-free operation, they moved on to the “fun” part of testing, now using sand (on a closed dust cover).
The cover does not keep everything out of the action, but it does help. Check out the video below to see the gritty action. (Pun very much intended)
*Note- Some NSFW language is in the video. Use appropriate caution.
