No Need for Any Other Trigger - Keith

The SD-E came with my Barrett REC7DMR. Had never fired from a flat bow before, but now I don't care to go back to standard. 2nd stage cuts loose with perfect precision. It's a few dollars, but no sense in putting junk parts in your weapon.

Love it - james

This is my fifth geissele trigger and I like it the best. I have three of the ssa-e's and a super scar and they are all superb triggers. But like I said I like this the best. I have mounted in my LWRC Razorback 2 and will be putting this in my next LWRC as well. Again couldn't be happier with Geissele. Also check out the airborne charging handle best I've felt out there and I'll be buying another one for sure.

Favorite Trigger of Dozens - Tyler

I've shot dozens of high end aftermarket triggers, and spent months in research trying to find the best option for me. Geissele triggers appeal to me since they are SOCOM approved and combat tested, and have proven reliable due to superior engineering and the use of full power springs.

This trigger is the flat-bow version of the SSA-E, so for those who like a flat bow trigger shoe, and a lighter trigger, this is absolutely the best option on the market.

I've shot my carbine to 650 yards on steel, and it's everything I want out of a trigger at that distance. I shoot 2 gun, and wasn't sure if I would love the trigger at close range targets, but I do.

I can maintain .18 splits with this rifle, and I'm not a very fast trigger puller. Any AR I own will have one of these triggers in it, period.

Another fantastic product from Geissele, again, with detailed installation instructions. Buy one!

Day and Night - emkay

I got this trigger for my AR-15 as its first upgrade during the recent Memorial Day Sale. Thank you for the great price AND a bunch of stickers and patches. Oh and a hat!! Very generous indeed.

The installation was done before my pizza was ready. I finally had an opportunity to shoot my rifle today. All I can say is that I am glad that I bought this trigger. The factory trigger from Daniel Defense was not bad but was too heavy. I had watched many review videos on Youtube and all said the difference with this tigger was day and night compared to the factory trigger and I now know what they meant by that.

LOVE IT!!

My next upgrade from Geissele is the buffer spring kit. Cannot wait!!

Outstanding trigger - Brian

Just buy one if you are thinking about it. It's perfect. I have two and need to pick up a third.

Impeccable feel - Eli

Could not be more happy with my purchase of this trigger. Took me about 15 minutes to install and it feels like a dream. Everything i thought it would be plus some. This trigger exponentially improved my Sig 516. Took me almost a year to make a decision. I could go on and on with how happy I am. Point is, dont buy anything else.

March 18th, 2017

Perfect. Period. - G

I have bought two of these. One for an SPR build, and another for a BCM recce style build. Outstanding for both. Precise, consistent, crisp. It never gets old.

AMAZING - Clancy

Installed the Super Dynamic Enhanced (SD-E) trigger in my 18" AR build and am happy to say it was more than I was hoping for. Takes your rifle to the next level.

*****WORTH EVERY PENNY I SPENT***** - Sonny

Worth every penny I spent,the installation was quick & easy and am very happy with my choice.I also ordered the charging handle which has been on back order but it's worth the wait,next christmass I'm getting
the 7" Super Modular Rail and there quality is next to none also.Once you order any of there products theres no turning back.

Simply, perfect - Matt

My trigger and swag kit (which was an awesome touch btw!) processed and shipped in a very satisfactory amount of time considering the time of the year. Everything showed up perfect and I replaced my Spike's "Enhanced Battle Trigger" with this. I put around 1500 rounds downrange with the EBT and think it is a pretty solid piece considering what it is. But the SD-E is definitely on another level. I popped it in and got to the range. Only fired 120 rounds, but I'm already forever sold on this company's triggers. Words do not describe its feel with any justice- it's a "must experience" if you're even only remotely an AR guy.

I watched Bill's trigger selection video a couple times before I chose the SD-E, and I'm confident this is perfect for my "SPR" - and likely nothing will top this. I bought this on a Black Friday deal, but I'll definitely be purchasing a couple more, deal or not, for my other rifles. Worth every penny. Can't wait to shoot it more!

Outstanding Trigger - Albert

I had some concern about the Flat trigger with my B.A.D. lever, however with my glove on there is absolutely no issue. Can't wait to take it to the range. I may never shoot my other mil-spec rifles anymore...lol. Thanks to all @ Geissele Automatics for a truly Outstanding Great American Pennsylvanian Product. ps., love the hat !

SD-E AR-15 - Chuck Riley

I have two of these triggers installed on my Colt 6920's. I purchased my first about 2 years ago and recently purchased a second for my new rifle because the trigger is so nice. Without mentioning the trigger, I've let several people shoot my rifles and the first thing that they say is "man that trigger is awesome". Nothing but good news with this trigger. Perfect for the range, duty, and home defense. Love the feel of the lightening bow.

Number one quality -- nothing by the very best - Moish

Wow what an amazing trigger. It's everything that's advertised and more. Very smooth first stage. Clean break on the second state. This is a great all around trigger as it's not too lite, and not too heavy on the pull. Easy to install. Worth every cent.

SD-E Excellent trigger - Joe

After literally months of research, the decision was made to purchase the SD E for my Colt Competition AR. While the rifle was designed for 3 Gun, it is primarily used for shooting off a range bench informally, medium distance (100-300M). While it took a while to decide on a two stage trigger, the take up is smooth and the second stage wall is easily managed and very evident. The break is like glass. It was absolutely the best choice for my purpose.
The flat trigger works very well for the shooting style employed. Finger placement is consistent and easily replicated.

Thank you for a great product!

Outstanding Quality - Josh

I was in a local high-end gun shop last week when the sales guy started pitching me a custom trigger. I listened to his spiel, then ask how they stack up against a Geissele SD-E. He only hesitated a moment before quietly telling me "I prefer my geissele."

June 14th, 2016

Superior product!!! - Daniel

Getting the handguard next, amazing craftsmanship!!

Buy with confidence - Brian

I am an avid coyote hunter that needed a trigger that was fast and smooth, yet could maximize accuracy on longer shots if needed. The SD-E is probably the best answer to an AR hunters needs.

The SD-E is light enough for load development/accuracy testing in the summer, yet not too light for a gloved finger in the Fall. Smooth with a very solid wall and crisp break of the second stage. ULTRA consistent, pull after pull.

What does it feel like? After you pull through the first stage to the wall, another pound of pressure and the hammer falls. Reminds me of a well tuned 700 bolt trigger when the second stage breaks. Need to shoot fast...... just pull straight through, and you will shoot plenty fast for ANY field application.

Certainly not quite a match trigger, a High speed match makes more sense there. But the SD-E is no doubt the best hunting and general fun shooting trigger I have ever used. The straight trigger bow is easy to adapt to, and after only 600 rounds or so its easily my favorite and preferred bow. I am sold all around ..... so wanna feel like you got what you paid for? Pick up an SD-E !

Wow, another excellent product. - Patrick

After buying and falling in love with the SD3G trigger. I decided to buy this SDE. I am incredibly happy with it. It does not matter what caliber or set up I drop it into, this is a superior trigger. Once again I can't wipe the smile off my face. Fast, accurate, dependable, and so smooth. A trigger that literally makes the shooter better many times over.

the best purchase experience - BINH

This is my first trigger from geissele. I must say, this is the best buying experience that i had ever. Geissele went above and beyond to give the best service to their customer. I am sold on this company. On to the trigger, it is worth every penny. A smooth first stage, with clean second stage break. the cycle is repetitious on every pull. everything is so consistent. zero overtravel. geissele trigger is my one stop shop for all my ar platform rifle. Thank you so much being for being such a classy company. v/r, blt.

Its exactly what your looking for! - jim

I am very happy with my choice. Was a little nervous but chose the SDE for my AR 10. Installation was pretty straight forward. Recommend watching the video. First day at the range, feeling the initial first stage and then POW. The trigger really does break like a crisp icicle. Big smiles on this trigger. I'm back on the site because I'm getting a second for my M4.

Pick one up - Rudolf

So it was just after New Year's and I was brimming with excitement when the large white envelope arrived in my mailbox.. the swag pack enclosed with it literally made me laugh out loud with joy. I touched the flat trigger and it's workmanship and sturdiness was more than I expected - it had a very solid weight to it, a far more durable feel than the mil-spec trigger I was used to.. I'd previously watched Mr Geissele's installation video and I was ready.. The slave pin was handy.. The lube tube was trick.. The installation was easy and made me feel like a master armorer.. My local shooting range disappeared around me.. I was now a sniper in a hot LZ.. Smooth, smoooooth first stage, then the absolutely impeccable, predictable carrot-like break in the second - EXACTLY as advertised.. Expect tiny groups.. Receiving, installing, and running the Super Dynamic-Enhanced on your AR setup will put a smile on your face that only the Best of the best big boys toys can.. Pick one up.

It's worth every penny - Chayson

This was my first Geissele trigger. I bought it for a 18" varmint build. I was very sceptical of the price tag and what I might end up with. I was wrong. From the first pull of the trigger I was convinced. Everyone that has shot my rifle has since bought a Geissele to fit their need. One friend had bought a popular yellow single stage trigger for a precision rifle build of his own. He has since sold it and has a SD-E. If the price is still a bit out of your range wait for their holiday sale, especially Black Friday. But they'll sell out quickly.
With the free shipping and the Swag package that comes with the triggers what's not to love about this company and their products.
Never have I been treated so well as a customer.

Premium quality trigger. - Russ

Short: supreme quality, excellent reliability, safety of having two stage (against unintentional discharge), excellent precision in the lightweight second stage.

Long: I've had this trigger for a little over a year now - several thousand rounds through it - and it is unmatched in its excellence. It's by far and away an incredible improvement over my stock colt trigger, and going back to one (or any stock trigger) will never be an option. Bottom line, a trigger is about feel - it's the link between you and the release of that projectile, and much like the throttle on any vehicle, you've got to have a smooth and flawless link between man and machine. It was an easy install (30min), and it's been a coveted upgrade amongst friends and fellow shooters who try it out. Honestly, most are deterred by the price tag, however, my opinion is that I will pay a premium for quality, and nothing else - I won't pay for a name, for hype, for trends. I will pay a fair price for quality, and this trigger is of the utmost.

Excellent for Precision AR - Michael

Very happy with this trigger, is an understatement. Did I mention how much I liked it?
With this trigger and the Ergo Tactical Deluxe grip my trigger finger is the perfect relaxed position for precise, accurate and comfortable shooting. Perfect.

Perfect Fit in my PA10 .308 build - von R

Pro: This is the trigger I always imagined. Perfect fit in the Palmetto State Armory PA-10. Pull on the 1st stage is clean and firm, 2nd stage was a smaller pressure that I could hold till I felt the target was aligned and a strong feeling releases the hammer. Installation was similar to standard trigger, I did not need to remove the selector.
Con: I want more triggers
Observation: AR-10's have no standard, lots of talk on-line about difficulty fitting this trigger in the PA-10. PSA also made a TAC-10 that appears to be a Armalite clone lower and I suspect that that lower may need modification not the PA-10 Lower. Mine is a perfect fit. I have put a couple of hundred rounds through it without any failures to feed, or eject, and it is very accurate.

September 17th, 2015

Love it - Randy

Easy to install, works great. This was my first trigger upgrade, always used whatever came with the rifle till I shot a friends rifle with the exact same trigger. I will say I am more accurate with this trigger and it makes shooting a little bit more fun. The only reason I gave it 5 stars is because they didn't have six.
