The Geissele Super Semi-Automatic (SSA-E®) trigger is a precision-tuned version of the legendary SSA trigger with lighter trigger pull for long-range accuracy.
It features a reduced trigger pull when compared to the SSA (3.5lb vs. 4.5lb). The 1st and 2nd stage pull weights result in a trigger with a smooth, light 1st stage take-up and a crisp, candy cane-like 2nd stage break.
To put it simply - this is the best trigger out there when marksmen-level accuracy is critical, and reliability is a must.
About the SSA-E
- The Geissele SSA-E has a pull weight of about 3.5 lbs. There is 2.3 lbs. on the 1st stage and 1.2 lbs. on the 2nd stage. The pull weights and sear engagement are non adjustable by the shooter.
- Trigger and hammer are made from quality tool steel.
- Sear surfaces are cut by a wire edm machine. Sears cut this way are very accurate and the non-directional surface finish of the wire edm gives a smooth trigger pull without the associated grittiness of directional machining marks left by a milling cutter.
- The initial force needed to start the disengagement of the sear surfaces is low and the force linearly increases at a low rate. This helps the shot to fall at the initial point of aim and aids in building shooter confidence in his weapons ability to put the rounds where his sight is pointing.
- The Geissele SSA-E trigger allows the shooter to slap through the trigger pull on close in shots but also set up a long range shot with a crisp trigger break.
- A full force hammer spring is used for quick locktime and positive ignition of all types of ammo. There is no lightened hammer spring used.
- The hammer is lighter than a standard AR15 hammer. The lightened hammer favorably decreases locktime over a standard hammer from 8.5 to 5.1 ms and increases accuracy of the weapon.
Easy to install - the SSA-E is a simple design that is very similar to the original M16 trigger.
- The number of parts is identical.
- There are no adjustment screws to come loose.
- All springs are captive; they will not get lost during disassembly in the field
- The entire trigger can be dissembled for cleaning (no rivets or staked parts)
- The trigger can be installed without removing the safety
- Sear engagement is pre-set from the factory.
- Hammer and trigger pins are a close slip fit into nominal receiver holes so the trigger can be installed and removed withrudimentary tools.
- Triggers come with a slave pin for the trigger/disconnector assembly for easy installation.
Patented design ensures accuracy and reliability
- The Geissele SSA is a 2 stage trigger where there is generous overlap of the sear surfaces which contributes to safety and a low tendency of any inadvertent movement of the trigger to discharge the weapon.
- The Geissele SSA has a patented pseudo sear that is almost identical to the standard AR15 single stage sear. However, this secondary sear has surfaces that never touch during normal operation.
- This sear prevents the hammer from falling unless the trigger is pulled. The secondary safety sear contributes to shooter confidence in dynamic/vehicle situations where a fellow shooter's muzzle may cover position the weapon can never discharge unless the trigger is pulled.
- Trigger timing is robust and parts have been sized to operate with a certain amount of wear to the working surfaces. The trigger is designed to operate in dusty, abrasive environments that cause wear.
- Size: Standard Mil-Spec Pin
- Trigger Bow Type: M4 Curved
- Weapon Platform: AR15/AR10
- Does not fit HK416 weapons with firing pin safety.

Great price easy to install and man what a great feeling. Purchase one you will be very happy
I purchased this trigger when the cheap drop-in trigger did a 3-round-burst out on the range. Yeah, I had the weapon unloaded and heading back into the case when the range officer walked up to me.
I haven't taken the trigger to the range yet, but it's passed all of it's function checks, is nice, smooth, and crisp. If I don't come back to edit this posting, assume this trigger is wonderful.
The trigger is priced well. I've never shot any of the $300+ triggers, but outside of being adjustable I can't imagine what else they might do better than this one.
The trigger shipped the next business day, and arrived in an acceptable time frame. Great work AT3!
Trigger is much better than a standard factory one. Only wish I'd bought the fully adjustable model. All my bolt guns have Jewels set around 1/2lb. Not much compares to those. But for an AR, this trigger works ok. There simple to install and run fine. I have four of them.
awesome product great price will do Business with them again.
Installation was straightforward. Feels good on snap caps. Looking forward to trying it out at the range.
