This video details an expert-level AR-15 full auto barrel meltdown test conducted by Mrgunsngear Channel, comparing a Melonite (nitride) treated barrel against previous chromelined barrel tests. The test involved firing over 1,000 rounds continuously to assess barrel durability and reliability under extreme heat. The speaker, demonstrating significant expertise in firearm testing, meticulously documents malfunctions, component wear, and the visual effects of extreme heat on the barrel.

Quick Summary

An AR-15 Melonite barrel underwent a full auto meltdown test, firing 1,069 rounds. Despite the extreme heat turning the barrel 'shiny white,' post-test inspection revealed good rifling and only slight gas port erosion. The test concluded due to cook-offs and severe reliability issues, highlighting heat's impact on firearm function.

Frequently Asked Questions

How many rounds did the Melonite barrel withstand in the full auto meltdown test?

The Melonite treated AR-15 barrel in the test fired a total of 1,069 rounds during the full auto meltdown phase before the test was concluded due to cook-offs and severe reliability issues.

What was the condition of the Melonite barrel after the full auto meltdown test?

After cooling, the Melonite barrel's rifling appeared very good, with only slight erosion on the gas port. The original black Melonite finish had turned a 'shiny white' due to the extreme heat experienced during the test.

What types of malfunctions occurred during the AR-15 full auto meltdown test?

During the test, the AR-15 experienced numerous malfunctions, primarily failures to eject and double feeds. These issues became more frequent as the rifle's heat increased, impacting its reliability.

Did replacing the bolt improve reliability during the AR-15 meltdown test?

No, replacing the bolt at 382 rounds did not improve reliability. The firearm continued to experience numerous malfunctions, indicating that the issues were likely more related to the extreme heat affecting overall system performance rather than just the bolt itself.
