Sx4 drill and tap?

[Rem Man]

  Hello guys looking for an answer as I'm reading yes and no. I am trying to find out if you can drill and tap a Winchester sx4 because of the aluminum alloy receiver? I am looking to put a fastfireiii on mine. Thanks!

I have not seen that gun.  Now 80% of guns now days are aluminum.

Is that a yes or no for the SX3 or the SX4??
