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.

Are hammer & trigger pins included ?
Bigfoot on May 3, 2018
BEST ANSWER: Yes it has mil spec sized pins included with the trigger. Not the colt larger pins from years ago.
Is it possible to get the furniture in O.D.G or F.D.E?
Spoke on May 2, 2018
BEST ANSWER: PSA will NOT swap items or colors on any of their packages. I've asked from time to time and gotten polite but firm "NO."
So to be clear, the Giselle replaces the fire control group, correct?
Matthew B on May 19, 2018

Will this work with an sba3 brace in a pistol configuration?

BEST ANSWER: This will work with any AR.223 5.56 lower
Would this work for a .224 Valkyrie complete upper as-is? If not, what parts do I still need besides a stripped lower?
Randall E on May 12, 2018
BEST ANSWER: Yes, this will work with a 224 Valkyrie complete upper. The only other thing you will need is a 6.8 SPC magazine, stripped lower receiver, and some ammo. Links below.

Does this kit have a safety ?

BEST ANSWER: SKU: 7793002- PSA AR15 MOE Lower Build Kit - Without FCG - Black - 7793002
- This kit does include the safety.
will this support a AR/10 .308 platform?
Robert M on Jul 30, 2018
does this kit come with a firing pin? i know it says it doesnt but it also says it doesnt come with a trigger which it obviously does
nakomis m on Oct 29, 2018
BEST ANSWER: There is no firing pin that comes with this kit. The firing pin is part of the bolt carrier group. This is a drop in kit and comes with everything needed to install if you already have a complete lower and will operate properly with a complete upper and bolt carrier group.
Will this kit work with the 9mm platform?
Julia L on May 23, 2019
BEST ANSWER: Yes, this build kit will work with the AR-9 platform. You'll need to use a 16" 9MM barrel though as this is a rifle build kit. As far as I know PSA has not released a pistol build kit with the Geissele trigger
Will there be a version of this it with the SSA instead of the SSA-E? ( I prefer the heavier pull weight of the SSA )
Crew A on Apr 23, 2019
BEST ANSWER: No it has not been sold with the ssa yet and I’ve been keeping a eye on these sets. It’s still a great set none the less especially for the money when it’s on sale
Will this trigger fit my KS-47 lower? If not what similar trigger weight would you recommend?

Great Buy!
I purchased this kit about a year and a half ago, while I was slowly accumulating parts. This purchase was one of two that made my rifle amazing. As it was my first build, I found the separate packaging of the parts a nice touch. With that said, the trigger made this purchase. This trigger is amazing, crisp, and light to the touch. I mainly use the rifle for hog hunting. I am in the process of building another rifle and I am glad this is back in stock. Will honestly be purchasing another one as my other build progresses. As one that has relied on customer reviews for a lot of components for my build, this was a vital purchase for a high end rifle.

Awesome trigger !
For the price, I bought this mainly for the SSA-E trigger and considered the lower build kit as an added bonus. I had never used a Geissele trigger before, but am glad that I bought this. It is super crisp and very consistent. I ended up buying a second trigger to go into my other AR.

Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger & PSA AR15 MOE Lower Build Kit - Without FCG
Love the Geissele SSA-E very nice. The Mag Moe stock pretty sloppy rattles like a pile of bones have to use some tape on the buff tube to tighten it up the rest of the kit usual Palmetto quality.
