Laser holder for bug-a-salt
Version A without screws - only clip. Made for laser diameter 19mm - the clip diameter is 18mm, so it sits very tight.
Version B with screws, you will need 3 screws M5x20mm (or M5x25mm) with M5 nuts. Made for 19mm laser diameter, but its adjustable, so I think, that laser diameter between 16,5mm and 19,5mm could work.
IMPORTANT NOTE: the axis of the holder is parallel to the barrel's axis, so you NEED a laser with an adjustable beam angle, see pictures for the details. It works only if you can adjust the axis of the laser.
