Details

The Geissele SD-E trigger installs in your lower receiver in the same way that a Mil-Spec trigger is installed. It uses a standard .154” trigger and hammer pin so it will fit in any Mil-Spec stripped lower receiver. It features a flat trigger bow that gives you more leverage to reduce perceived trigger pull weight and improves the tactile feedback so you can feel the reset and pull the trigger faster. Not only does it work in 5.56 or .223 AR-15 rifles, but it works in .308 AR-10 pattern rifles. Each trigger is precision EDM wire cut from heavy duty tool steel with a durable black finish giving you the reliability and durability you can depend on.

Features:
  • Uses Mil-Spec .154” trigger pins for maximum compatibility with lower receivers
  • Works with 5.56/.223 and .308 AR pattern rifles
  • Designed as a target and precision trigger
  • Smooth, consistent two-stage trigger pull
  • Has a 3.5lb total trigger pull weight
  • EDM wire cut from heavy duty tool steel
  • Features a flat trigger bow that reduces perceived trigger weight and improves tactile feedback
Note: Trigger pull weights are approximate and may vary slightly between rifles.

When building or upgrading your AR-15 rifle, one of the most important components is the trigger. There are many triggers out there so you must ask yourself what are you are going to do with the rifle. Are you going to use it for plinking at the range, home defense, competition, or long-range precision shooting? The answer of this question will help you to understand what trigger you will need. The Geissele Super Dynamic Enhanced (SD-E) Trigger is designed specifically for target and precision shooting while still being reliable enough to be used in combat situations. It features the same short length of pull and quick reset in the 3-gun competition version, but has a 3.5lb trigger pull. Although it is a two-stage trigger instead of the hybrid system, it still has the flat trigger bow for quick and controlled shots. The SD-E is the perfect upgrade to your AR-15 weapon system that will greatly improve your accuracy and reliability.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.

The most important upgrade for any AR-15

by -

Just picked up my third Geissele trigger. Waiting for these to go on sale takes patients but if you can wait the deal is worth it. Prior to this SDE I have bought SSA-E triggers. This is the exact same trigger but with a flat trigger instead of the SSA;s curved one. Also my first flat trigger. It feels great, buttery smooth like it should. I thought I would have a hard time adjusting the flat trigger but after a few hundred rounds I got used to it. Which do I like better? They are both great and perform exactly the same, the flat just has a different tactile sensation while pulling the trigger. Tightens groups beyond 100yds and like adding a turbo engine for up close engagements.

Get 'em while on sale! Clean & Crisp Break

by -

As you would expect from Geissele is a quality product. I love the 2-stage trigger because it allows me to fine tune my shot before pulling the second stage. The first stage is very smooth and predictable and the second stage break is very crisp and with minimal reset. The flat bow is a personal preference so YMMV.

Outstanding !

by -

The SDE is an outstanding trigger !
<br>
<br>Initially I was a little concerned thinking "would it be too light ?"
<br>
<br>It's not - its just right !
<br>
<br>I've bought five of these triggers over the past 2-3 years when they are on sale.
<br>
<br>Once you try this trigger - its all you will want to use.

Excellent trigger

by

My wife surprised me with this this past christmas and now that i have spent some time with it i thought i'd chime in. I think you are either going to love or hate a flat trigger...so try to test before you buy if at all possible. With that being said, it might be the finest ar trigger i have ever shot. Break is exceptionally clean and reset is very minimal. Is this worth the extra cash over getting an rock river? Absolutely. If you are budget conscious the rra will be great, but this is a totally different level of quality and precision.

Super Dynamic Trigger/Super Dymamic Retailer- P.A.

Amazing trigger, too put it lightly(No pun intended) People tried to talk me out of the flat trigger I'm glad I didn't listen. Also people said it's too light get the SDC-don't listen to them it's awesome. I wanted to order from factory to get the swag kit but they were closed around holidays. Besides that the deal Primary Arms gave me I can buy my own hat and bumper stickers. Also PA was exemplary service even when I was asking for better deal. Of course everyone knows by reading the reviews they are super fast shippers. Thanks PA!

SD-E

by

This trigger is light! Very easy to install and the flat trigger bow looks great on my v11. A must buy if your looking for a precision trigger. Primary had a great price I couldn't turn down and the shipping was very fast.

Best trigger ever.

by

The Geissele Super Dynamic Enhanced Two Stage Trigger is, in my humble opinion, the best trigger out there. It has a clean break and very light stages. A must for long-range target shooting. All of my AR-15s have been upgraded with these triggers.

My groupings are much tighter with the new trigger. Shipping was fast and the customer service was excellent as always. Thank you guys!

Geissele SDE Trigger

by

This is the second SDE I have purchased and I am very satisfied with both quality and performance. Removal of my manual safety was required on both installation, but easily accomplished. The trigger breaks like "Broken Glass" at the poundage advertised.

Amazing!

Perfect trigger

by

PA got my order Wednesday afternoon, and I had it before noon on Saturday with USPS. The trigger installed in 15 minutes with help from YouTube. I already put 150 rounds through with the new trigger, and it functioned flawlessly. It is very light, but the two stages seem to keep premature firing in check. I would recommend this trigger to anyone looking to improve their groupings significantly.

Great Trigger

by

This is the second one I have purchased. It is exactly what I want from a trigger on a precision AR.

It's the best trigger I've ever shot...well worth every penny!

Geissele SD-E

by

This is an excellent two-stage trigger. The pull weights are exactly as advertised, and the second stage produces a nice, crisp break. Indeed the break is reminiscent of breaking a candy-cane, as advertised. I had debated whether to go with the Combat or the Enhanced version (fearing the Enhanced would be too light), but having decided on the SD-E, I am more than pleased. The trigger is light without feeling unsafe, and while the second stage is short and a mere 1.2lbs, it is definitively enough to feel as though one can control one's finger at the second stage for as long as the shooter finds necessary. The flat face gives the shooter the option of placing the finger as low as they choose on the trigger. Thus, if the shooter so chooses, he or she can reduce felt trigger pull by gaining leverage lower on the trigger. This is a fantastic feature. Overall, I am very satisfied.

SD-E

by

This is the one! Everyone said "you shouldn't use the Enhanced on a battle riffle"i beg to differ, i can't stand a stiff trigger! This trigger is very safe, i have punished it and there are "O" problems with it for any scenario. Out standing product! I even used my KNS Gen2 anti roll pins .155" which are .001" under size of the .156" pins that come with the SD-E and they work perfectly. I wish Geissele would produce there own anti-roll pins @ .156" but we are talking about .001" here! My only worning would be, if you plan on using this trigger with a very worn/used lower that has seen several thousand rounds you should probably use Geissele's pins and possible the SD instead of the SD-E. My lower has only seen about 1K.

Geissele and P.A. Is a winning combo!

by

The trigger is a great two stage. I love the flat bow. Smooth as butter with the candy cane like break like the description implies. Now PA's service would get 10 stars if that was an option. Stupid fast shipping. PA is always the first place I check when I'm in the market!

Too Light For Me

by

This trigger looks cool but was waay too light for me. Even on a bench completely still, I found myself letting unintentional rounds go. If you have jittery hands or plan on shooting with gloves, definitely go with the SSA.

Great trigger

by

Very crisp, well-designed trigger.

Smooth as silk!

by

no regrets going with Geissele, smooth and easy to install. Good instructions too!.

SD-E

by

Well, what can I say? It does exactly what it says it does. Very light & consistent pull, and a crisp break. I love it! I would not get this for anything but precision shooting.

SDE

by

TOTAL pull weight is 3.5 lbs. - second stage is actually about 1.5 lbs.

Great Trigger

by

This trigger as expected is great like and Geissele trigger. I really enjoy the flat trigger, and it makes it feel lighter that it is.
