I have a Tavor and just put in a Geissele trigger.
With a factory 7 lb trigger, I was shooting a shotgun pattern of 6 MOA at 100 m using AE223 ammo.
Now with the Geissele trigger, I am shooting a 1" wide but 6" long vertical group at 100 m using AE223 ammo.
I am just using a sand bag at to support my fore end and I am shooting from a bench.

Any suggestion to reduce the vertical spread?

Have you dry fired to see if your rifle moves when you squeeze the trigger ?

+1. Excellent suggestion. To bring it even one step further, load a few mags with one dummy round in each. Do not keep them loaded exactly the same, so make sure the dummy round is always in a different spot. Cycle them through the rifle (live fire at the range, of course), and you will see what is happening...you won't know exactly when the dummy round will be chambered, so when you squeeze that trigger, since the dummy round doesn't fire, you will be able to see how you and the gun are moving...hopefully this will help solve your issue. Good luck...
 
Did the dry fired and the sight picture was not moving.
I am using a 8x scope and I had checked the scope for a solid mounting as well. I will dry the dummy round idea and see whether it changes my sight picture.
 
Dry firing without live rounds, expecting not to go BANG doesn't really kick in that flinching reflex 'cause your mind knows what to expect.

Not sure if you're flinching? Have a buddy load up a mag for you but include a dummy/snap cap round somewhere in the mag. You'll know if you're flinching when you pull the trigger on that snap cap.
 
Have you considered that it isn't the trigger that causes the Tavor to shoot poor groups?
What were you expecting? Change trigger and all of a sudden it would shoot 1-2 moa with cheap 55gr?
Try some different ammo, consistent accuracy usually costs money, if your ammo isn't costing you $1/round or more chances are you're not going to shoot the groups your rifle is capable of.

The flinch test mentioned above is a great indicator to tell you if it's you causing the problem but chances are it's the combination of using a rifle that is known for 1.5-2 moa at best and using cheap ammo. There aren't many rifles out there that will shoot better than 2-3 moa with bulk 55gr FMJ. At least you're not using Norinco 55gr and expecting good groups though.
 
Very much doubt you're flinching with a semi-auto .223. Possible, but unlikely.
What's the pull on the new trigger?
Change ammo first. AE is ok, but if you're not reloading you really need to try a box of as many brands as you can to find the ammo your rifle prefers. Don't think I'd bother with match ammo. What bullet weight you using?
The hardness of the sand bag can affect the shot string too. Plus you need to pay attention to your breathing. If you're taking a breath while shooting, you're changing the aiming point too.
Remember that a Tavor isn't a target rifle and it's oddly shaped for shooting off a bench to start with. So where the sand bag goes is kind of important. I'd be thinking right behind the flared bit with no pressure but the weight of the rifle.
 
Make sure you don't move your head to get the recticle on target, especially when looking through high power scope, ie, parallax.

If your forend is solid on the bag, it should negate flinching issues. I would try a few boxes of other ammo too. There's a review on here that had Horandy 55 grain zombie at under 2" - try and find a box of that and make sure you don't yank the trigger.
 
The barrel was not heating up much as I was shooting in -10 C.
All the shooting was done in the same afternoon. The barrel was not hot to touch (barely warm).
AE223 was 55 grain FMJ. I tested the shooting with the factory trigger (7lb pull) with the AE223 ammo. The 5 rounds group was a shotgun pattern of 6" grouping. The rounds landed everywhere in the 6" diameter grouping.
I popped the factory trigger out and changed it to the Geissele trigger (5.5 lb pull). I used a Caldwell bag to support the fore end. The 5 rounds grouping went to a 1" wide and 6" long grouping below my point of aim (instead of a shotgun pattern). I shot another 5 rounds group and again the grouping was 1" wide and 6" long grouping below my point of aim.
Changing the trigger changed my grouping shape. This is very unusual to me.
I just want to get a 2 MOA grouping.
