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.

Geissele Trigger

by

I feel these are the best triggers on the market in terms of price & simplicity in design. Their reliability & function are outstanding.

Awesome

by

Already have one of these guys, and knew I had to buy another for my .308 build. The pull is light but crisp and clean. Incredible trigger, this while be going into my DMR/precision build because I love the flat bow and the light trigger pull.

Geissele Super Dynamic Enhanced Two Stage Trigger

by

Awesome Product. Awesome Retailer. Awesome Shippoing

Exactly as wanted

by

Been wanting one for a while after trying several different ones in friends AR's. And being on sale just pushed it into the purchase box that much faster. I like the first stage for the take up feel, and then the brisk short final wall to release is exactly as wanted.

Great Trigger

by

Excellent trigger (I currently use both an SE-E and SD-C). Wouldn't recommend the SD-E for a combat/carry rifle but it is definitely the trigger for a longrange 'shooter' or scoped rifle (400m +). Thanks for shipping in a box vice the old method of using a padded envelope.

Super Dynamic Enhanced.

by

For an AR unless you are doing long range target, varmit or 3 gun competition, it is too light. Materials, construction, all top notch. First stage great, second way to light for a carry rifle in the field. I then purchased the SSA 2 stage and it was perfect. Less money too and now I am stuck with this as cannot return once opened.....

GSS SDE

by

Hands down best trigger I've ever used.

Great deal, great service, great product!

by

I ordered a Geissele SD Enhanced trigger on Primary Arms' Black Friday Special (which beat everybody else's price by $30.00).Shipping was VERY reasonable.I went to Vegas for a week the day after I ordered it. When I got back home, it was at my P.O. Box. Easy enough.With a little help from YouTube, the trigger went right in. So easy a caveman (with YouTube) could do it.Haven't had any range time with it yet, but it feels AWESOME!!!! Sooo much better than the heavy, long, gritty, "multi" stage trigger that was on my AR.One thing to mention about this trigger, it's the same internals as the SSA-E, but with a flat bow. If you've ever thought that the conventional curved bow on your trigger felt "too close", you'll love the flat bow!I'll be doing more business with Primary Arms in the future!'Yotes beware!!!!

Great trigger, great service

by

I'm pretty new to primary arms, but since finding it, I'm having a hard time staying away. Thanks for the excellent service. As for the trigger, you cant go wrong with it, smooth, great break. 1st time straight trigger, nice feel.

Outstanding upgrade

by

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

Amazing!

by

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

Smooth as silk!

by

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

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.

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.

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!

Geissele SDE

by

The trigger is fantastic. Quick and informed transaction from Primary Arms. Wish everything could go so well.

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.

Great Trigger

by

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

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.

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.

SDE

by

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

Great trigger

by

Very crisp, well-designed trigger.

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.

Amazing!

by

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