Overview
This sight bead is designed for hunters and shooters who want a straightforward front-sight upgrade with a secure, indexed mounting style. The Metric Bradley version uses an all-white bead and follows the same “bead-on-a-block” concept described for the line, placing the bead on a steel base for a more positive fit. It is a practical option for replacing or refining a front sight setup without adding unnecessary complexity. The product is offered by Bradley Gunsight and is intended for use where a simple, dependable sighting point is preferred.
