In ON, the matches will have targets at distances from 3 m to 100 m for the most part. Many people running dual sighting systems such as scope and red-dot or scope and iron-sights. Many of the targets will be IPSC mini targets (potentially partially masked) and maybe steel. Most seem to run 1-6 scopes but they seem slightly slower than the red-dots or holo-sights. The scopes rule past 50 m.
We may see some matches reaching out past 200 m next year.
