Savage 110 FCP .338 Lapua stocks and chassis

[backcountryguide]

This is my first Savage so if someone could set me strait I would appreciate it. Stockys has a T4 in stock for 110 center feed Detach Mag System. Will this work for my rifle or does the bottom medal differ from a standard long action Savage? As far as a chassis goes it appears XLR is my only option at this point am I correct?

MDT, Cadex, AWT, probably forgetting a few others.

I have a 110 in the AWT (applied weapons tech) chassis and love it.
