hi glen, i have the hotech sca, which has a self centering mechanism, which i'm not entirely convinced about. you twist a compression ring which in turn compresses and expands some rubber rings in the adapter.
i literally just checked, and when i checked the laser position, then loosened and rotated 90 degree's and performed the check again the laser dot was not in the same place. so this suggests that it's either not well collimated or it's the self centering mechanism is reliable / repeatable.
Rich.
