RPM 35mm High Rail Cap Diving Board - Flat Dark Earth
The RPM 35mm High Rail Cap Diving Board in Flat Dark Earth is a rail-mounted accessory platform designed to expand your optics setup without replacing your existing scope rings or cantilever mount. This cap allows you to add secondary aiming devices—like red dot sights or laser rangefinders—to your magnified optic system, giving you a compact, lightweight solution for shooters who want layered aiming options without the bulk or cost of a complete new mount. If you're running RPM's CLR series rings or Bravo/Delta cantilevers, this diving board integrates seamlessly into your existing platform.
What makes this accessory stand out is its simplicity: it's a direct cap replacement that works with all existing RPM products, and installation uses the same screws that came with your original rings or cantilever. No special hardware to source, no gunsmithing required. Whether you're setting up a precision rifle for long-range hunting, a tactical carbine for three-gun competition, or a dedicated range gun where you want the flexibility to switch between magnified and unmagnified sighting, this diving board gives you that modularity without re-mounting your primary optic.
The Flat Dark Earth finish blends with modern tactical carbines and hunting rifles, and the design philosophy—compact and lightweight—means you're adding capability without sacrificing handling or balance. This is purpose-built gear for shooters who already trust RPM's products and want to leverage that investment.
