Archery bow risers and bow accessories having leveling devices
Archery bow risers and bow accessories are provided which comprise integrated level devices for use in, e.g., tuning and installing accessories on archery bows such as compound bows. For example, a bow sight device comprises a mounting bracket configured for attachment to a bow riser, and a sight housing adjustably connected to the mounting bracket. The mounting bracket comprises a first level device and a second level device. The first level device is configured to enable a user to level the bow riser in a first direction, when the bow sight device is attached to the bow riser. The second level device is configured to enable a user to level the bow riser and the sight housing in a second direction which is orthogonal to the first direction, when the bow sight device is attached to the bow riser.
