I have fired the issue Tavor, I noticed no difference. I fire my Tavor right next to friends with their ARs and aftermarket triggers, yet I routinely score higher than they do.
Also, I work in the gun industry. I came to the conclusion long ago that the American mentality, in regards to trigger pull, can be summed up to this: "They don't want anything heavier than 2-3 lbs and they don't want to move their finger more than a few millimeters".
Stock AR triggers are just fine, as are stock Glock triggers as well. Yet, I sell and install several aftermarket triggers for both of these weapons on a regular basis. The SIG P250 pretty much failed out of the gate based on its DAO trigger, and even though I hate the gun on general grounds, the trigger is just fine to me.
Of course, this is just my opinion, I could be wrong.
