While these may look like the original PRW's, looks can be deceiving. They took this tried-and-true design and made a few upgrades, which include a new easy-installation ring-top design, an improved keeper and a bigger contact area with the base for a precision fit. All while maintaining the classic PRW functionality, look, and ruggedness.
The Weaver- and Picatinny-compatible cross-slot design of these steel rings is updated to be stronger and to give them more contact with the base for added stability.
