The Wicked Ridge Invader 400 is a TenPoint-family bow that ships with three Alpha-Nock Match 400 arrows, per its Lancaster Archery package listing. Wicked Ridge is a TenPoint brand, so it takes the Alpha-Nock like a modern TenPoint.
It is an Alpha-Nock bow. Do not fit an older Omni or a flat nock: on the narrow modern barrel the string can slip under a non-Alpha nock and dry-fire the bow.
