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.

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.
The pull weight is not adjustable. At what weight is it set?
ButchN on Apr 21, 2019
Will this fit in a Aero Precision lower?
MARC M on Dec 22, 2018
BEST ANSWER: Marc, I have his same trigger in three different manufacturer's lowers (S&W, Ruger, and TCT). All work brilliantly! By the way, this price is unbelievable, I paid the 240 or so. So if the lower is within normal factory specs (the holes for the pins), I see no reason why it would not fit and function.
Carry on smartly, Bruce
With this trigger how many’s shots will fire off of one complete pull?
Jeff M on Dec 28, 2018
BEST ANSWER: One. Unless you have a select fire full auto weapon you are putting it in, in which case you’d probably not be asking this question.
Is this a double tap trigger?
Shane R on Apr 20, 2019
BEST ANSWER: This is a two-stage trigger as far as I know double tap is a shooting technique not a style of triggerEnter an answer to this question.
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.

So... Is this SSA-E 2.76x better than a MBT-2S?
AZHTfreak on May 17, 2019
BEST ANSWER: I'm not familiar with the MBT-2S trigger but i would highly recommend the SSA-E trigger. Positive resets, smooth action and pulls. I've not had a single problem with the Geissele triggers I have.
What is the difference between this trigger and the SSA ?
Michael H on Nov 23, 2018
BEST ANSWER: Of these two-stage triggers the largest difference is the break. SSA breaks like a carrot (some give) and SSA-E breaks like an icicle (crisp). I am very satisfied with the break of SSA-E and would highly recommend its use in a precision rifle build.
Will this trigger work in a smith & wesson m&p 10? Thx.
John S on Jul 28, 2018
BEST ANSWER: If the holes are matched up in same area. They trigger group pins are 5/32. Take a pair of calipers and measure the distance on a standard ar-15 then measure your mp-10
Will this work with an AR-9?
Jgriffin on Nov 23, 2018
BEST ANSWER: Yes it will, but it might have too strong of a strike and snap the firing pin. (happened to my NFA AR9)
Will this fit in a sig 716 patrol rifle? (AR-10)
T T on Nov 9, 2018
BEST ANSWER: Yes, but I would recommend the SSA trigger instead. The SSA-E is so sensitive that with the recoil of the 716 it will sometimes bump fire.
Can it ship to California?
John H on Dec 23, 2018
BEST ANSWER: I do not believe CA restricts semi-auto AR-15 triggers so they should ship it to CA. Add it to your cart and checkout. PSA will inform you if there is an issue shipping it to your state.
Will this fit my Ruger AR-556? Is it a noticeable improvement over my stock trigger?
Ken S on Dec 21, 2018

mike on Nov 23, 2018
BEST ANSWER: it will not. however, there are certain CMC Triggers that will work
Do you have a trigger this style to fit a Veper 12 ?
LISA B on Sep 1, 2018
BEST ANSWER: I do not believe any company produces a 2-stage trigger for the Vepr 12. As you probably are aware ALG Defense makes a line of Vepr 12 triggers and none of them are 2-stage to my knowledge.
What if anything will I need to install this trigger assembly in an ATI OMNI HYBRID lower? The reason I ask is the trigger pins in the stock trigger look like small flat head screws. Note: I haven't removed them to see what's behind them yet... is it possible they are just there to make sure the pins cant fall out?

One freakin smooth trigger!
I love Geissele triggers! They’re everything you want in a smooth, easy, and precise trigger pull. I have at least 5 Geissele AR triggers for upcoming builds, and two installed in my AK’s.

Nite and day from the mil spec. A little pricey but it usually will go on sale on holiday weekends. Worth the $ either way
5 minutes later and it's a done deal
Next build I will give the 3Gun a shot

Fantastic Trigger
The last time PSA had these on sale I ordered 2 of them. I must admit that even though they were on sale I was hesitant to spend that amount of money on a trigger, as I've honestly never had any problems shooting my AR's accurately with standard triggers, but after installing and shooting the SSA-E triggers I will never again hesitate to order one again. These triggers are just awesome. Smooth as glass with a final break that is simply beautiful. Using the same rifle upper and ammo I shot one group of targets with s standard trigger then I shot another group using the lower with the SSA-E trigger. The group shot the standard trigger was very good but with the first shot the group shot with the SSA-E trigger tightened right up and just as important the wonderful feel and control with the trigger made me feel even more confident of accuracy shooting my rifle. Simply amazing trigger. If you're thinking about trying one don'e wait, just order it. You will not be disappointed.

Love this Trigger
I have several 2 stage triggers in my AR platforms. I must say the Geissele lives up to its reputation. This has a very nice primary pull with an even quick break on stage 2. I would recommend this to anyone looking for a great 2 stage trigger for their AR platform.

Great throw
I have bought JP, CMC, Hyperfire, Rise armament, and giessle. There are many different triggers for many different jobs. Giessle would be my top pick for a trigger that’s durable and refined. A great pick for a enhanced battle trigger. Full power springs and high end tool steel. Other triggers look to be made of cheaper softer steel.
