Well to start with cosmetically the filler cap / and the bolt handle are fluted ,and the logo is bolder.
Also where the barrell is connected to the breech block they have fitted a follow on fluted slip which smartens things up a bit.

As for the internals I was told certain mods or upgrades have been made but the spokesperson wouldnt elaborate.

The bolt certainly feels smoother and the gun feels a tad lighter in comparison to my older version but that could be just me thinking so.
