Holosun is testing the waters on a new shotgun weaponlight that mounts in line with the magazine tube. I suspect many shotgun users have dreamed about being able to mount a light on the end of the magazine tube over the years but switching for this light location has always been the fly in the ointment. The activation switch set up for this light has not been revealed at this time.
Steiner already makes this kind of light it isnt new
