Geissele SSA-E X trigger with lightning bow is an easy drop-in upgrade for AR-15 and AR-10 platforms where accuracy and reliability are critical. This two-stage trigger uses a standard .154” trigger and hammer pin so it will fit in any Mil-Spec lower receiver. It features a lightning trigger bow that's designed with a flat face and curved bow to spread pressure over more surface area, allowing better trigger control and accuracy. Each SSA-E X trigger has a nano-coated body and hammer with a Chrome Nitride disconnect to protect against wear and corrosion while giving you the reliability and durability you can depend on.

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.

Worth it

by -

I swapped from a drop-in Timney trigger to this Geissele after multiple issues of the trigger not resetting from shoot suppressed for longer competitions. This trigger has performed flawlessly through multiple matches.

No Brainer

by -

Worth every penny if your upgrading or building out an AR platform this is definitely a great but.

Crystal break, just about the right pull weight

by -

It one of the best geisselle trigger

Amazing trigger!


I’ve used some really good triggers and there is no question of which one of them is my first choice. The SSA E-X. The pull weight and break and even the shape is really really sweet! For me it is what I compare other triggers to. Hard to have only one.

SSA-EX - Take a Bow

by -

Crisp, breaks-like-a-glass rod release, Lightning-fast reset. This trigger lives up to the billing. The best "drop-in" improvement you can make to your carbine - and was an absolute steal at Primary Arms' sale price.

Best Geissele Trigger yet

by -

So yes this is the best trigger from Geissele it had a shorter reset than any of its other triggers.

Phenomenal trigger!

by -

Geissele has (in my opinion) some of the best triggers out there on the market. This one is no different! I love it, half of my firearms have a timney, the other half are geissele! This SSA-E X is probably my new favorite! So crisp and clean and absolutely consistent.
