See how a standard AR-15 upper holds up to 830 rounds in 8 minutes

This past week, Eric (YouTube’s IV8888) put a standard AR-15 upper on a M16 lower through a crazy torture test. He was testing the overall durability with extreme usage on a few specific products including the Sharps Balanced Bolt Carrier Group with Relia-Bolt. As you’ll see, our bolt was up to the challenge and exceeded expectations.
