This video demonstrates the severe consequences of firing an AR-15 with a bore obstruction. While a mud obstruction was safely cleared by the projectile, a stuck military cleaning rod resulted in catastrophic failure of the upper receiver. The test highlights the critical importance of ensuring a clear barrel before firing to prevent dangerous malfunctions and potential injury.

Quick Summary

Firing an AR-15 with a mud-obstructed barrel can be safe, as gases may clear the obstruction. However, a cleaning rod lodged in the bore poses extreme danger, leading to catastrophic failure and potential injury.

Frequently Asked Questions

What happens if you fire an AR-15 with a mud-obstructed barrel?

In a test, firing an AR-15 with a muzzle completely plugged with mud did not cause catastrophic failure. The gases preceding the bullet cleared the mud, and the rifle remained functional and safe to use.

What are the dangers of firing a rifle with a cleaning rod obstruction?

Firing a rifle with a cleaning rod lodged in the bore can lead to catastrophic failure. In a test, this resulted in the upper receiver shattering, parts flying off, and severe damage to the firearm, posing a significant safety risk.

Are military barrel caps safe to fire through?

Yes, military-style barrel caps or plugs are designed to be safely fired through. They are intended to keep debris out of the barrel during transport or storage and will be expelled by the projectile.

What is the most critical safety rule when handling a firearm?

The most critical safety rule is to always ensure the firearm's bore is completely clear of any obstructions before firing. Never assume it is clear; visually inspect it every time.
