I’m not sure it’s too bulky for hunting - it’s hard to know without more details of size and weight.

I know guys that will happily mount a 57mm headed torch that runs 2x18650’s on their rifles.

The zoomable LED’s are good - most of my hunting is done with a B158 or B158B and the zoom function is very handy.

It just depends if the small lenses five enough range for hunting - many hunters will want to be able to identify game and shoot to about 200m.

This is stretching it with the red XP-E2 even in the B158 IMO so I’m not sure how a smaller lens will work.

I have a B168 here and the range is not as long as the B158 because of the smaller lens.

I am sure the T16 would be fine on shorter range rifles.
