Mag Dump Fixes Malfunctioning Gun

Published on June 7, 2023
Duration: 0:52

This guide details a rapid firing technique, often called a 'mag dump', used to address potential break-in issues with AR-15 platforms. The video demonstrates this method on an Aero Precision upper receiver experiencing bolt lock-back failures. The technique involves firing a full magazine quickly to stress the components, potentially resolving minor malfunctions and ensuring reliability after a break-in period. The speaker, identified as an intermediate practitioner, suggests some components require this high-stress event to function optimally.

Quick Summary

A 'mag dump', or rapid firing of a full magazine, can resolve AR-15 malfunctions like bolt lock-back failures by completing the component break-in period. Testing the suspected faulty part (e.g., an upper receiver) on different lower receivers helps isolate the issue. This technique is demonstrated by Elliott Delp as an intermediate troubleshooting method.

Frequently Asked Questions

What is a 'mag dump' and how can it fix an AR-15 malfunction?

A 'mag dump' involves firing an entire magazine as rapidly as possible. This high-stress firing can help break in new firearm components or clear minor obstructions, potentially resolving issues like the bolt failing to lock back on an empty chamber, as demonstrated with an Aero Precision upper.

Why did the AR-15 bolt fail to lock back after firing?

The bolt failing to lock back on an empty chamber can indicate a break-in issue with the firearm's components, particularly with new uppers. Testing the upper on different lower receivers, as shown in the video, helps isolate the problem to the upper itself.

What is the importance of a break-in period for firearms?

Some firearm components, especially new ones, may require a break-in period involving a certain number of rounds or specific firing sequences, like a 'mag dump', to achieve optimal reliability and function. This ensures parts wear together correctly.

How can you troubleshoot AR-15 malfunctions across different brands?

To troubleshoot, swap components between different firearm platforms. In the video, an Aero Precision upper was tested on PSA and Daniel Defense lowers. When the malfunction persisted, it confirmed the issue was with the upper receiver.
