SX4 question

[Tidewater Tom]

My son has been hunting with my old Remington 1100 this year, but I want to get him a Winchester SX4 for next year.  I want the 3.5" chamber and the MossyOak Bottomlands camo.  I really want to get a gun that's drilled and tapped, although I hear good things about the Burris Speedbead.  I'm wondering which model comes drilled and tapped or do they all come that way now?  I saw a thread on here where some folks purchased SX3s that were drilled and tapped, others had some that weren't.

Not sure if this helps but I know the SX3 has the NWTF model and it has a cantilever mount. I have that gun and it's been flawless.
