Sight apparatus for use with firearms are described herein. An example sight apparatus described herein includes a first swivel element removably coupled to a second swivel element. The first swivel element includes a first aperture coaxially aligned with a second aperture of the second swivel element to define a passageway. A coupling element is removably disposed within the passageway to pivotally couple the first swivel element relative to the second swivel element. A retainer is operatively coupled to the coupling element to engage at least one of the first or second swivel portions to prevent movement of the coupling element along a transverse axis of the passageway.
