Which Geissele trigger for DD MK18?

I would like to upgrade my Daniel Defense MK18 (10.3" barrel) to a Geissele trigger but am having trouble deciding which one. Given that it's a shorter barrel AR15 more suitable for CQB I was thinking the SSA-E may not be the best choice since it's good for long range precision. But now I'm wondering if it would improve the shorter barrel's accuracy at longer range -- making it more versatile. I've read the SSA, which is a little heavier and breaks not as crisp as the SSA-E, is an excellent all around trigger. Lastly the S3G resembles more of a single stage trigger and is better for speed rather than accuracy -- which sounds like it may be more fun but I do want a degree of accuracy too. Then there is a "straight bow" version of all 3 of these triggers which makes the pull feel lighter.

Please keep in mind that I have an Eotech red dot sight paired with an Eotech 3X magnifier and I'm not an experienced shooter.
Can anyone weigh in on a good fit for my setup?
 
+1 For the SSA-E. I just put one in my 14.5 AR and my groups tightened up and I also had zero issues shooting in CQB type situations with the trigger. I've only put about 100 rounds down range with it but I do notice a difference and am a big fan of a two stage trigger. Previously I was shooting a stock DD trigger and at first the SSA-E felt to light but after some dry firing and actually putting some rounds down range it feels just fine. I think it will definitely improve your accuracy and group size regardless of barrel length. I think the pull weight is approximately 3 1/2 pounds so if your looking for something slightly heavier the SSA might be a better choice at 4 1/2 I believe.

SSA or SDC, same trigger mechanicals but different trigger shape (curved vs. flat) for a CQB gun you want the higher trigger weight. Still very smooth and very good trigger. The 4.5 lb weight is the min I would go for a CQB/working rifle.
 
I'd say go with the S3G. I have the same optic set up as you on my 14.5" AR and the S3G trigger makes a huge difference wrt accuracy. It just depends on what type of shooting you want to do as to which geissele trigger to go with. With a 10.3" barrel, I don't think you are going to get much more accurate with one any more than another.
I wouldn't think of the S3G trigger as speed vs. accuracy but more as improved speed AND accuracy. The clean, consistent break of the S3G will tighten your groups up without a doubt.
As has been said many times before though, these triggers are so nice they kind of ruin you for using lessor AR triggers.

Arms East list having them in stock.

I've got the SSA in my DD v5 and I can't go back to stock again. I'm going to pick up a SSA-E for another rifle for more bench shooting. Never tried an SSA-E so this will be a first. Now to find those in stock. :p
 
For range shooting like, or ... 3gun ... v drill..... target not pass 500y... witch one... SSA SSA-E or S3G that the real Q !!!!! if there something esle beter for that purpose tell it :p
 
If you're shooting mostly bench, I'd probably opt for the SSA-E which is what I'm going to do. I have the SSA in another rifle and it's no slouch either. I don't think you can go wrong with either SSA or S3G with dynamic style shooting.
 
So if V-drill CQB and 3gun like shooting SSA-E is to avoid ? when it will getting warmer outside ill try to find some people with Geissele trigger an see what I prefer..it'S just to hard like this to make a choice.....
 
I use a ssa-e in several of my rifles that I use for 3 gun, service rifle and semi precision shooting. It is a versatile trigger and you will not be disappointed.
 
SD-3G officially turned mine into a machine gun. The flat bow trigger makes it feel 1lb less than the S3G.

Add a Surefire MB556k, now watch rounds all gather in one small circle.
