Why Choose the Seekins X-Cap 30mm?
The X-Cap is a replacement top cap for Seekins scope rings, machined from aerospace-grade aluminum. It lets you refresh or upgrade the upper half of your rings without replacing the whole set, and it is a handy spare to keep in your range kit.
Like the rest of Seekins’ ring system, the X-Cap is held to tight tolerances so it seats evenly on the scope tube and spreads clamping force without marking your optic.
Installation Tips
Remove the old cap, wipe the scope tube clean, install the X-Cap with the original cap screws and torque evenly in a cross pattern to your scope maker’s recommended value.
How to Choose the Right Ring Cap
Choosing optic mounting hardware starts with three questions: what diameter is your scope tube, how much elevation do you need, and how high must the scope sit to clear the barrel? Match the tube size first (30mm, 34mm or 35mm), then pick the lowest height that gives the objective bell clearance. If you shoot past 600 yards, a 20 or 30 MOA base or mount gives you extra elevation travel. Finally, think about weight and durability. Seekins hardware is machined from aluminum and anodized, so it stays strong and light without corroding.
Built by Seekins Precision
Seekins Precision is based in Lewiston, Idaho, where the company designs and machines its rifles, actions and accessories. That in-house control means every part is held to tight tolerances and checked for quality, so the gear you mount on your rifle performs as reliably as the rifle itself.

Taking care of your gear keeps it working for years.

A light coat of oil on steel parts prevents rust, while anodized aluminum only needs a quick clean.
