Add To:

Built on the chassis of the Geissele SSA, the Super Semi-Automatic Enhanced (SSA-E) provides enhanced trigger control and weapon accuracy while maintaining the robustness and reliability of the combat-proven two-stage trigger. The SSA-E’s reduced first and second stage pull weights result in a trigger with a smooth, light first stage take-up and a crisp, candy cane-like second stage break.

It has a simple design similar to the original M16 trigger.  There are no adjustment screws to come loose and all springs are captive, they will not get lost during disassembly.  The entire trigger can be disassembled for cleaning and can be installed without removing the safety.

The SSA-E is ideal for use in precision Squad Designated Marksman type rifles where weapon accuracy and reliability are critical and a non-adjustable drop in trigger is desired.

Is this trigger the same as a binary trigger ?
John S on May 27, 2018
BEST ANSWER: No, I actually swapped out my binary for this trigger instead. For the money, you get a better and more practical trigger. The binary was fun, but not really useful unless you like mag dumps

Would this work in a large pin colt? Or do they have one that will. Thank you
Bob A on Jul 4, 2018
BEST ANSWER: No it will not. This is a .154" small pin. You need a .174 large pin. Just Google search geissele large pin trigger. This is a phenomenal trigger by the way.
Will this fit my DD M4A1?
Patrick K on Jul 16, 2018
BEST ANSWER: You should be fine. Geissele states on their site that their triggers will fit all mil spec lowers. I have eight and have never had an issue. This is my favorite trigger by far.
Does anyone have this in a pa10 gen 2?
sean r on Jul 16, 2018
BEST ANSWER: I have a SSA-E trigger in a PA10 gen 2. Works like it should, the same as if it were in a AR 15.
Will this fit an Anderson Arms lower?
Ramiro E on Jul 16, 2018
BEST ANSWER: I have had experience with Anderson lowers but I didn’t use this trigger. But based on experience I see no reason why it wouldn’t work. I have use other Geissele triggers with Anderson lowers with no issue. I don’t think you’ll have a problem with this trigger either.

Gary C on Jul 16, 2018

Upgrade your trigger, upgrade your shooting and accuracy
With a 2 stage trigger featuring a 2 lb initial pull with a crisp 1.5 lb. to 2 lb. break, this is definitely a drop-in trigger to get. Replacing your standard or entry trigger or even an advanced trigger you previously bought this Geissele SSA-E is perfect for those who are shooting for fun, bench shooting, or hunting. With a quick reset after pulling this trigger is smooth and crisp

Best trigger on the market
I have bought more than a few of these over the years and Palmetto is the best place to buy them! Install of these triggers only takes about fifteen minutes, maximum. The triggers are just about perfect for precision shooting. Excellent two stage and with a perfect reset.

Tremendous item
This is great. 5 minutes to install and such an impressive improvement. Worth the money and even better when on sale. I will get more to upgrade all my lowers.

Works great, but I am glad I got one on sale!
This trigger features a smooth pull with a crisp break and positive reset. It is very expensive, however, for what it is. When I have used it more, I will be able to decide whether it’s worth the extra $100-150 more than an ALG Defense ACT with a JP full-power spring kit.
