Frequently Asked Questions

What are the key steps to installing a Geissele SSA-E trigger on an AR-15?

The installation involves removing the old trigger pin, using a slave pin to hold the new trigger in place, inserting the trigger pin, then installing the hammer and its pin. Proper alignment and lubrication of all contact points are essential for smooth operation.

Why is a slave pin used when installing an AR-15 trigger?

A slave pin is a temporary tool used to hold the trigger securely within the AR-15 lower receiver during installation. This prevents the trigger from falling out before the actual trigger pin can be inserted, simplifying the process.

Is it easier to install the hammer with or without a slave pin on an AR-15?

It is generally recommended and easier to install the hammer without a slave pin. This allows for more direct manipulation and better alignment of the hammer with the pin holes in the receiver.

What is the importance of lubricating the trigger group components?

Lubricating all silver contact points and springs within the trigger group after installation is crucial for ensuring smooth operation, reducing wear, and maintaining the longevity of the trigger mechanism.
