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 every work with a 7.62x39 build, planned on a plain jane lower build kit. Already ordered a wolf heavy spring. But would love s touch more refined trigger. Any suggestions?
Nis L on May 5, 2018
BEST ANSWER: Yes. For this build to work the firing pin needs to be 24 thousandths linger for Russian ammo
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
will this Geissele SSA-E trigger work smoothly on a psa ar9 using their ramped BCG?

BEST ANSWER: You shouldn't have any trouble fitting that trigger
Will this fit in the Palmetto State 308 PA-10 lower?
D W on Jul 8, 2018
BEST ANSWER: Yes it should.. I have put several geissele triggers into both pa-10 & pa-15 lowers, never had any issues.
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 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.
Will this fit my DD M4A1?
Patrick K on Jul 16, 2018
BEST ANSWER: If the DD M4A1 is a MIL SPEC AR 15 platform rifle, yes, it will fit.
Will this work in my bcm ar15 and spike tactical ar15?
Gary C on Jul 16, 2018
BEST ANSWER: It should work fine in both as they are mil spec AR-15 Lowers. I have this trigger installed in three different mil spec lowers and it works great.

Some Colt lowers have larger diameter pins and require a different trigger part number 05-171
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 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

Does what I needed it to do
Easy to install and does just What I wanted it to do. Reduce trigger pull! My 204 ruger hits golf ball targets out to 200 yds consistently.

Great on a S&W MP 15
I bought this to improve the trigger on my AR15. I was amazed first by how easy it was to install. I have no gunsmithing experience. I Googled a YouTube video and replaced the trigger while watching it. Easypeasy. I was also amazed at the difference in the ease of the trigger. I have now replaced 4 other triggers in other guns.
