I haven't fired the Tavor 7 for groups with 168gr FGMM yet, so cannot comment as to whether IWI managed to get the accuracy down to 1.5 MOA with match ammo as they have claimed. The "rework" that IWI did was to take the accuracy from 3 MOA (considered to great for North American tastes) down to a consistent 1.5 MOA with match ammo. We shall see, but my initial experience with 150 gr South African surplus battlepack ammo was guite positive. I had no problem ringing an IPSC silhouette at 300m and later 500m. The latter was a challenge with my 1-8x Trijicon, but the Tavor 7 eventually got it done and rung. I would guess that I was getting approximately 2 MOA out of the SA surplus ammo.
