Frequently Asked Questions

What tools are needed to install a Geissele SSA-E trigger?

You will need a punch set, a slave pin (or another punch to use as one), a mallet for gentle tapping, and firearm lubricant for post-installation maintenance. Ensure the firearm is unloaded before starting.

Can I install the Geissele SSA-E trigger without removing the safety selector?

According to Geissele's instructions, you typically do not need to remove the safety selector. However, depending on the specific tolerances of your lower receiver, you might find it easier to remove it for better access.

How do I ensure the hammer spring is correctly installed with the Geissele SSA-E trigger?

The hammer spring's 'ears' should be positioned on top of the trigger pin. Avoid trying to feed them underneath the trigger pin, as this is a common mistake that prevents proper function.

What is a slave pin and why is it used in trigger installation?

A slave pin is a temporary pin used to hold trigger and hammer components in alignment during installation. It simplifies the process by keeping parts from shifting, making it easier to insert the actual trigger and hammer pins.
