RPM Diving Board rail cap FAQs

What does the RPM Diving Board do? 

The Ruffs Precision Manufacturing Diving Board is a special top cap for your scope mount. It lets you add other accessories to your rifle, like a rail-mounted laser rangefinder or a secondary red dot sight, right on top of your main scope.

Will this fit the RPM scope mount I already have? 

Yes. This rail cap is made to fit all existing RPM scope mounts. This includes all CLR series rings and all Bravo and Delta cantilever mounts.

Should I choose the High or the Low height? 

That depends on what you want to mount.

• For mounting a laser rangefinder, you must choose the High rail.
• For mounting a red dot, check your scope. If it has a tall knob on top (a high turret), choose the High rail so the red dot can see over it. If it has a short turret, the Low rail is the right choice.

Is the RPM Diving Board strong? 

Yes, it is very strong. It is built in the USA from a tough material called 6061-T6 aluminum. It also has a special hard coating to protect it, called a Type III hard anodize.

Does it come with the screws I need to install it? 

No, this part does not come with screws. It is designed to be a simple cap replacement, so you will use the exact screws that are already holding the top cap on your current RPM mount.
