Surefire X-Series head lego?

[akula88]

Ever since Surefire introduced their fixed-head X-Series, it's been rather difficult to get definitive answer on doing a lego or swapping of compatible heads.

I'm interested if I can still swap the head of S2 Stratum to a P1R Peacekeeper or P2X Fury body.

Also -- which aftermarket vendors have X-series heads still available?

There are some 3xCR123 bodies made by FM that are Fury head comparable.
