A while back, Doug did a review of the Kel-Tec SU-16; this included the SU-16A and SU-16B.

I am curious to know if any one (especially Doug) has tried any of the other Kel-Tec SU-16s since they have come out. It appears that there is now a 16A, 16B, 16C, 16CA, and 16D.

How do these newer models compare to the original SU-16A and SU-16B? Would Doug still prefer one of the originals or are their new models actually "improved"?

Finally, does Doug still prefer Kel-Tec as his semi-automatic chambered in .223 or has he moved to something new altogether?
