Fieldcraft 270win Mag box size?

[tdot]

I have the opportunity to pick up a Barret Fieldcraft 270win, I'd buy it with the intention of swapping barrels to a 280ai. Does anyone know the length of the mag box?

The only info I can find online says 3", but I'm assuming/hoping that only relates to the SA options and not the 270win or 30-06.

I would say 3.4" would be very close. It's based on the Forbes 24 action with a 3.375" mag box.
