Crisp Reset
Excellent trigger upgrade for my M&P II Sport. A little more sensitive, but once I got used to it, it is a great upgrade. Quick and crisp reset. Great buy, great quality.

Love, love, love this trigger
Like all of the Geissele triggers I've purchased, this trigger is everything it's advertised to be. Clean, crisp break, and the straight blade looks awesome. I installed this on an AR-15 with a Vortex Spark II red dot sight and the it's amazing how quickly I can acquire the target and get off repeated, accurate shots. If you're even thinking about building a gun for fast, clean follow up shots with a great, consistent feel. Stop looking... you've found it!

amazing
By far my favorite trigger on the market. Comes with 2 different weight springs which is really nice cause the 3.5 is more like 3 lb. pretty easy to install. great fit and finish.

quite a trigger
I've primarily used Hyperfire triggers up until now. I just got the SD-C and think I may be switching all of my triggers to these (other than my pcc). The two-stage pull is much more forgiving in terms of accuracy and finding the break. I feel much more confident using this trigger in a home defense role than my Hyperfires. Also, this trigger was SO much easier to install than my Hyperfires - literally took 10 minutes from start to finish in a new lower. Geissele seems to be the gold standard for reliability and is touted throughout the industry, so I'm glad to finally join the bandwagon. And, Brownell's had hands down the best deal with both a sale price and promo code.

Best PD or instantaneously controllable
A fine trigger at the bench, an outstanding trigger for extremely fine work where instantaneous break completely controlled fire is needed. I own two and use mine on what are the equivalent of high-power AR platform space guns in .223 Rem for PDs out to about 500 yards off tripods and sticks. Small intermittently moving targets off only marginally stable rests. The trigger must break the instant that you think is should. These deliver. Also a good trigger for shooting standing on your hind legs, same requirements. The SD Enhanced is slightly but noticeably better than their similar slightly cheaper curved trigger two stage trigger which is a good trigger in it's own right. I have never had a bump- fire in well over 5000 rounds. Acquire the target, take up the slack of the first stage, adjust the sight picture for perfect, this trigger breaks almost unconsciously in the middle of the thought that it's time.

Replaced my Timney
I really like this trigger for a hunting rifle. The light take up and crisp break are awesome and it's very safe for a rifle I carry in the woods and swamp. I like my Timney, but this is a better option for me and it took no time to make the adjustment from single stage to two stage. The Flat trigger is what made me try it, I think it works better with big hands.

Best there is.
I am a 3 gunner and didn't start winning matches until I added this trigger to my rifle. The press is not like a long range rifle but is easy to get super fast accurate double taps and have total control doing it. There is no finer trigger for 3 gun in my opinion and I've tried several.

Worth it
I have only had experience with mil-spec stock triggers and wanted a change. I did my research and decided to buy once cry once. The 240 price is steep but after the first shot all my tears were gone! Smooth pull breaks like glass. I just ordered a 2nd one when i saw that it was on sale.

Outstanding Trigger!
This is my first Geissele trigger. I can honestly say this is the nicest trigger I have yet to use. I love the two stage format. The first stage is pretty short and the second stage breaks super crisp with just a little extra pressure. It blows away any single stage trigger I have used. I don't know how this stacks up to other triggers in the Super Dynamic line, but I will definitely be getting another one of these during the next sale. I highly recommend!

3 Pound AR Trigger!
This is not an ordinary trigger. There is no comparison with a stock assembly. I was doubtful about the high price, but this is well worth the money. Trigger comes with two trigger springs. 5 pound and 3.5 pound. I tried both in a very light carbine I assembled with a 16" barrel, and a standard weight bolt assembly, standard weight carbine buffer and spring and a Spike's Tactical lower. The 5# trigger is super. Single stage, clean break. I love the flat face. Installation of the hammer was a bit of a struggle as my kit didn't come with a slave pin. Used a slightly undersized punch to align the hammer and spring with the pin holes, and cocked the hammer. Then everything fell into place. I had no problems on the range. Great feel. NO creep. Very short reset. With the 3.5# spring the trigger pull actually measured a little under 3# average using Lyman electronic gauge. With the short reset and light pull this trigger will bump fire if the trigger is feathered, as the instructions warn. Easy to avoid with a little practice, but I am working on a fix to eliminate the possibility. Groups are superb.
