Frequently Asked Questions

What tools are needed to install a Geissele trigger in an AR-15?

You will need the Geissele trigger kit components, a slave pin (often included), a punch set for driving pins, a vise with receiver block, and ALG Go-Juice lubricant for critical surfaces. A safety selector may need to be removed temporarily.

How do you ensure the hammer spring is installed correctly on a Geissele trigger?

The front of the hammer spring must be placed on the back of the hammer. The video demonstrates the correct orientation, emphasizing that improper placement can lead to installation issues or malfunction.

What is the purpose of the slave pin when installing an AR-15 trigger?

The slave pin is a small, specialized tool used to hold the disconnector in place while you drive the main trigger pin. This alignment is crucial for a smooth and correct trigger installation.

Where should lubricant be applied when installing a Geissele trigger?

Lubricant, such as ALG Go-Juice, should be applied to the critical engagement surfaces. These are typically the silver, uncoated areas on the hammer and trigger where the sear makes contact.
