RPM 30mm High Rail Cap Diving Board - Black
$84.99
The RPM 30mm High Rail Cap Diving Board is a rail-mounted accessory platform that transforms your rifle's existing optic setup into a multi-tool mounting solution. If you're running an RPM cantilever or ring system and want to add a secondary red dot, laser rangefinder, or other rail-mounted device alongside your primary magnified scope, this diving board gives you the real estate to do it without swapping gear. It's designed for shooters who want flexibility—hunters glassing at distance but wanting quick-aim backup, long-range competitors zeroing in with a laser, or tactical-minded folks who think in layers.
The genius of this accessory is its simplicity. It's a drop-in replacement cap that works with any existing RPM product in their lineup—CLR series rings and Bravo/Delta cantilevers alike—so there's zero guesswork about fitment. The hardware you already have from your original RPM purchase is all you need to bolt it on. No proprietary fasteners, no surprise compatibility issues. Just cap off your rail and start mounting.
Built by Ruff's Precision Manufacturing, the 30mm High Rail Cap Diving Board stays true to the brand's philosophy: purposeful engineering that doesn't add bulk or weight. Whether you're a long-range hunter layering in glass, a 3-gun competitor stacking optics, or a precision rifleman who refuses to leave options on the table, this is a straightforward way to expand your mounting options without a complete system overhaul.
