So Im hearing the new Tikka T3X's have an aluminum bolt shroud, doesnt anyone know if this will fit the older T3's? Are they available through Beretta?

1) yes.

2) HERE THEY ARE

Awesome, Thank You Sir.

No problemo.

RWE - awesome and, unlike the Tikka mags, don't cost a second mortgage to buy. Homesteader

Not much less than the aftermarket ones. And some of those actually look just as good or better.
