When building or upgrading your AR-15 rifle, one of the most important components is the trigger. The Geissele Automatics Super Semi-Automatic Enhanced X (SSA-E X) Trigger is built off of the chassis of the Geissele SSA Trigger to provide the enhanced trigger control, weapon accuracy, and reliability of a two-stage trigger. It features a reduced first and second-stage pull weight and crisp, consistent break so that you can build muscle memory to know exactly when the shot will be fired every single time. This results in a trigger that is both accurate and reliable. The Geissele SSA-E X is an all around great trigger that will enhance the capabilities of your AR-15 substantially.
