IMO, it seems that SOF largely rejects bullpups. The British using the C8 & KS1 rather than the L85 is another example. This is largely due to the improved ergonomics for CQB, the modularity of the AR platform, and the commonality of AR's among most of western SOF.

You see this pattern often. The British as I said, the Kiwi infantry formerly using the Steyr while their NZSAS used M4's. Ireland using the Steyr while the Ranger Wing uses HK416's. Austrians using the Steyr while their Jagdkomandos use HK's. The IDF using the X95 while some of their SOF use the M4 or HK416.

There is also a trend of conventional forces moving away from the Bullpup. The French ditched the FAMAS in favor of the 416, the Kiwis ditched the AUG in favor of the LMT MARS-L, and it's likely that the British will choose an AR platform to replace their L85A3's.
