The Owlkrown EyeKup Kit is a preset combo — pick your thread size and finish, and you get both the regular M-EyeKup and the Slim M-EyeKup in one purchase. Two profiles, one price, saving you $20 over buying them separately.

The Regular M-EyeKup offers a classic eyecup profile with a wider rim — ideal for shooters who prefer more eye relief or wear glasses. The Slim M-EyeKup cuts peripheral light more aggressively with a lower-profile design — preferred by shooters who want maximum frame line visibility. Together, they cover every shooting situation.
