Geissele Automatics Super Dynamic 3 Gun SD-3G Hybrid AR-15 Trigger .154"

Unless you're shooting long distance, this is by far the fastest and most controlled trigger available.

This is an excellent trigger for competition/target shooting as recommended by Geissele. It is definitely NOT suitable for any sort of duty use. It is extremely light and susceptible to bumpfires under certain conditions. While shooting long distance, I inadvertently let a 2-3 round burst go. The heavier trigger is advertised as 4.5 pounds, but there is a statement on the packaging saying it may seem lower on certain rifles. With this trigger being flat, the perceived weight seems to be significantly less the lower you place your finger on the trigger(physics!). I’m not trying to bag on this trigger, as I absolutely love it, but I will have to swap it over to a rifle that is not used for duty.

Best trigger that I have ever owned, hands down. Just as advertised by Geissele himself, it snaps like a carrot. I have read some of the negative reviews for this product and I have not had the same experiences whatsoever. Since installing this on my latest build I have seen noticeable improvements in accuracy, and I will probably put this trigger in every AR that I build moving forward.

I know everything about this trigger has been explained and repeated, but damn, I can't get enough of this thing. I have many different aftermarkets in many different rifles, but I keep coming back to this. My favorite. I already have two but need another. Primary Arms is killin' my wallet with these sale prices.

This trigger has serious hammer follow issues. It will not go bang when you pull the trigger at the "wrong time."

<br>I am not kidding and this is acknowledged by Geissele. When asked for a different model trigger they refused me since I did not buy from them directly.
<br>
<br>This trigger is advertised as fast shooting and reliable. It literally jams every ~8 rounds on double taps/rapid fire.
<br>
<br>STAY FAR AWAY. I shoot often and with a nice weapon, this is not a unique issue and Geissele is not standing behind their product.

<br>from PA: We have seen nothing but exceptional quality on this trigger and have never seen Geissle turn any one away. Give us a call and we will get this worked out for you.

Holy hell is this a light trigger. Have SD-Enhanced, a couple SD-Combat, and I thought both of those models were heavier than expected. I wanted something lighter, so I opted for the SD-3G. It is scary light. In ready other reviews I'm starting to think mine is lighter than normal. It will go in a bench rest only gun, because it is way too light in my SHTF 308sbr.

One word....WOW! This trigger is amazing, crisp clean break, using the 3.5lb included trigger spring, I haven't used a trigger as perfect, and FAST as this one. Hands down I'll be putting this trigger in my other rifles. I also love the flat bow, Geissle nailed this one.

Great trigger, had a nickel Teflon coated milspec that worked really well but I put lighter hammer springs in to decrease weight, started getting light strikes occasionally. Put this trigger in and I love it, just a tad lighter than what I modified my other to but this one seems so fast and has such a clean, surprising break that I love! Really helped tighten my groups up.

Just do yourself a favor and buy this trigger, already. I installed the lighter spring from the get-go and use this on my competition rifle. Those that have complained about bump fires, IMHO, are probably "slapping" the trigger instead of doing it properly and holding it back, then releasing the pressure until it resets. I can do rapid fire strings and have never had any issues with accidental/negligent discharges or bump fires. The trigger itself has a nice, clean, light break. The reset is what really sold me on this trigger--short, sweet, and tactile. The flat trigger face also helps lighten the perceived pull. Easy drop-in mod. Just do it!

Can't say enough about this trigger,even better as it was on sale. This ones in my SPR. Have a curved one in my Stag 3GL.

Love this trigger in my 300 Blackout. I have 4 Geissle triggers and this is my favorite one of all silky smooth and crisp break.

I installed this in my competition rifle. I had a CMC single stage trigger in it for a while prior to installing this trigger. The resets are great and allow for high rates of fire. I went ahead and installed the lighter spring right from the get-go. I never had any issues with negligent discharges or bump fire; I think as long as you don't slap the trigger and keep to the basics you shouldn't have any issues either. Primary Arms had a GREAT deal and shipped fast. What more could you ask for?!

This trigger is crazy quick. Short reset and fast. One drawback...precision shooting. When aiming for those 200-300yard shots for precision it sometimes bumpfires two very very fast shots. I'm sure following through and holding the rifle tighter to shoulder to fix this would suffice but I will be opting to go with a 2 stage SD-E Trigger.

I have other triggers but........ This is my favorite trigger hands down! I still like my Hyper fire 24C but this is nicer.

Love this trigger. Extremely fast reset. 3.5 pounds pull.You can rapid fire accurately with this.

THIS IS IN MY OPINION THE BEST 3-GUN TRIGGER ON THE MARKET. PA SERVICE WAS PROMPT.

When I saw this on sale I had to have it. All of the performance of the Tac-Con trigger at around half the price. With a smooth, short pull and an absurdly close reset this allows shooting at near full auto speeds. That being said it does take a little getting used to. If the thing refuses to stop burst firing you can switch out the trigger springs to gain an extra pound of trigger pull weight. Making it into a trigger I can almost recommend for combat/self defense use. I have yet to meet anyone who has regretted getting one of these triggers. 😊

Light pull, clean break, awesome trigger!

The SD3G moved to my #1 spot after the first few dry fires. Smooth, light trigger with super fast reset. I've shot dozens of triggers, including several Geisseles, and this one takes the cake. I have a SD-E on a scoped 6.8 SPC (my choice for a 2-stage precision trigger). The SD3G is just plain fun.

Nice and sweet, great reset, so nice we now have two of them

Hands down the best trigger for 3 gun or any shooting sport that requires a super fast reset for follow up shots!

This trigger is smooth!

I've run about 400 rounds with it through various cqb scenarios in a BCM 14.5" carbine.Couldn't be happier!Very smooth, even, pull with no creep or build.I had read about people having doubles with this trigger. I don't understand how this is even possible.They must be flinching / slapping the trigger or some other terrible habit to get it to double.It is definitely faster and much lighter than a Milspec single stage but I find it had plenty of resistance for me to "feel" it move after I began squeezing. (With the 3.5# spring)I find that the flat trigger bow gives me better feedback as the trigger starts to move.Geissele does not market this trigger for defensive or tactical use. I've been told this is for legal reasons due to the low pull weight. (Not sure if that's true)IMHO, this is the best cqb trigger I've ever had the pleasure of running myself.Shorter, lighter, faster.Bottom line.... Very impressed!Buy it!

Its true what they say that you get what you pay for.This trigger is all that and a bag of chips
