PSA AR-15 Complete Lower Magpul MOE Edition With Geissele SSA-E Fire Control Group - Black, No Magazine. Lowers may be Safe/Fire or Pictogram.


Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger:  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.

Fantastic Trigger, Loving it
Geissele SSA-E Trigger without question, great pull, a must have, working out issue as to why 223 ammo is FTL ( Failure to LOAD) every other shot and 5.56 ammo hanging every 5th or 6th round in brand new Mag-Pul Magazine.

Par excellence
My 3rd lower and as usual (mint condition). My 1st 2 stage Geissele trigger which is simply WOW smoothest pull I’ve ever felt. So typical of PSA quality products. I can’t say enough how impressed with their work. They are my favorite go to hands down.

Good value
I was a little skeptical, but PSA met all expectations. Shipping took a few days longer than most vendors, but PSA's FAQ section details that serialized items ship to a FFL after 7-10 days, and they took 8 days to ship mine, so, no real problem there.

The lower itself is great. One thing to note is that the stock is not the Magpul CTR, so it does not have QD points.

Fits well with my PSA upper with FN CHF barrel. Almost no slop in the upper/lower fitment. In case you're worried, as far as I can tell, the trigger is definitely the Geissele SSA-E 05-160, not one of the cheaper Geissele triggers that PSA uses in some of their other items.

Very happy with this purchase. Considering the trigger sells for no less than $240, $299 is a great deal for this package, and the trigger comes installed. If my experience is any indication of what you will receive, then buy with confidence.

Trigger is nice and smooth
Paired with an 18 inch 223 Wylde. Trigger is nice and smooth. Quality is excellent. Smoking a coke can at 200 yds.

Love it, very happy
My first AR build, found this lower at a great price at PSA. The roll pin and takedown pin were almost inoperable despite grease/lube and massive force, however PSA retains the 5 star rating because they sent new ones immediately when I contacted them. The trigger is like butter. The fit with the upper I bought is perfect even though the upper wasn’t PSA this time.

Great value but not perfect
Upon receiving my lower (NOT A BLEM) I was disappointed to find a tool mark/ small gouge in the finish as if they missed when installing the pin on the bolt release lever. :-/


Other than that great gun for the price I will be using it with a lightweight 16" PSA MLOK 556 upper .
