Israelis designed the TAVOR and X95 as an infantry weapon to replace M16. It is NOT a CQB weapon. CQB means close quarter battle which means you can almost look into the eyes and the facial expression of the people you try to do harms to.
Depending on your military, in general most militaries are happy their grunts can hit a 20"X20" target at 300m. That translates to a 4 MOA weapon is more than acceptable, given 2MOA error due to the user and other environmental factor. If you stretch it, a 6MOA gun can hit enough to give you a military qualification a pass with a 60% score.
And the myth that 2-3MOA is not accurate,,,,, most of the best rack grade AR15 out there are 2 MOA guns with the better quality mass produced 5.56ammo. No matter who makes the barrels or the guns, they are honest 2-3MOA system with mass produced ammo at the very best. Shooting hand loaded match ammo with 3 or 5 round groups doesn't really count, because this is not how these things are spec'ed out and the sample size is too small for each group . We are talking about 10 to 20 round groups.
