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.

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

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.

Awesome Product. Awesome Retailer. Awesome Shippoing
Exactly as wanted
by Travis Smith
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.
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 David Griffith
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.....
Hands down best trigger I've ever used.
Great deal, great service, great product!
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

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.
