These particular B-Square Vari-Clamp Adjustable Rings are designed to work as replacement rings with the vast majority of B-Square mounts and bases. The rings are in the standard 1-inch size for true versatility and offer a high profile.

Each ring in the set has two completely adjustable base clamps letting them mount securely to the rails. You can loosen or tighten the clamps based on your needs in order to secure them and complete your lineup for precision sighting. The rings hold four screws and tend to work with several heights due to their adjustable nature.
