Frequently Asked Questions

What is the main purpose of the BCM AR-15 reliability test?

The primary goal of this five-year test was to demonstrate the reliability of the direct gas impingement (DI) operating system in an AR-15 platform, specifically challenging claims that DI rifles are unreliable and require constant maintenance compared to gas piston systems.

How many rounds were fired through the BCM AR-15 without maintenance?

The BCM AR-15 rifle was subjected to 9,200 rounds of Federal American Eagle 55-grain ball ammunition over a period of five years, with absolutely no lubrication or cleaning performed during this extensive testing phase.

What issues arose from firing 9,200 rounds without cleaning or oiling?

After thousands of rounds, significant carbon buildup caused the bolt carrier group to become sluggish and seized, leading to feeding issues and requiring manual intervention to chamber rounds. The rifle also exhibited signs of over-gassing.

What ammunition was used in the BCM AR-15 reliability test?

The test exclusively utilized Federal American Eagle 55-grain ball ammunition in 5.56x45mm/.223 Remington caliber. This ammunition proved to be consistent and reliable throughout the entire 9,200-round duration of the test.
