Frequently Asked Questions

What tools are needed to remove an AR15 buffer tube?

The primary tool required is an armorer's wrench to loosen and remove the castle nut. A stable work surface and potentially a vice for pre-loosening the nut are also helpful. Ensure the firearm is unloaded before starting.

What are the critical spring-loaded parts to watch out for during AR15 buffer tube removal?

During AR15 buffer tube removal, be mindful of the buffer retainer detent and its spring, as well as the rear takedown pin detent and its spring. These small parts are under tension and can easily launch out and become lost if not handled carefully.

How do you safely remove the buffer and spring from an AR15?

To safely remove the buffer and spring, first depress the buffer retainer detent inside the receiver. The buffer and spring are under tension, so be prepared for them to move. Remove them carefully and set them aside.

Why would someone need to remove the AR15 buffer tube?

Removing the AR15 buffer tube is typically done when swapping out an adjustable stock for a fixed stock (like an M16 style), or when performing more in-depth maintenance or modifications on the lower receiver assembly.
