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.
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: Only one round will fire. It's a two stage meaning there is a short / light Paul of about 2 pounds to take up the slack and then it will stop until you increase the pull of your finger about 1 more pond for a nice clean break. This is one great trigger and worth every penny. It is amazing how much more accurate you are with a good trigger like this
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.

Catfish on Nov 24, 2018

Gary C on Jul 16, 2018

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 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 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 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.

mike g 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.
Will this fit my Ruger AR-556? Is it a noticeable improvement over my stock trigger?

Great Trigger. No Regrets!
I've used several modular, drop-in triggers (CMC, POF), so I suppose I'm sort of a trigger snob. The Geissele is easily the equal of any others I've tried.
For me, the hardest part was trying to decide, from the descriptions, which model would be best. After shooting a friend's SSA-E, I went for it.
Keep in mind that the SSA-E is quite light, and may not be the best unit for your particular purpose. But Geissele has a wide selection for different applications.

My Favorite
At this point, I’m not even sure how wany of these I own. Essily the best trigger I’ve found - Am currently looking to buy three more. They are a bit expensive, but worth every penny.

A rifle with a POS trigger is a POS rifle. This trigger will cure a POS rifle. Have purchased 2 from PSA, 1 for a 5.56 AR and 1 for a 6.8 SPC AR. Catch them on sale for added bonus.

Hard to beat this trigger!
When it comes to price, performance and reliability you're going to be hard pressed to find a better trigger. This trigger really performs even under some grueling conditions from classes and abuse from dirt. I've had other triggers with great feel but seen them fail when dirty where as this just runs without issue. You know exactly what to expect each and every trigger pull. I can speak highly enough about its reliability!

It’s and older model, sir, but it checks out.
Last gen geissele (without retaining pin) which is why it’s $100 cheaper than usual, but it’s a fraakin’ Geiselle SSAE. Buy it, you idiot.

Excellent 2-Stage Trigger
I bought this trigger (SSA-E) for a AR-15 build project which is intended for accuracy. I paired this trigger with a excellent barrel, BCG and Geissele Super-42 which 5 group shots are sub to one MOA. I will buy more of these for other rifles.
