KDG SIDELOK, Cantilever Scope Ring Mount Modular Kit, 34mm, Black Finish SID5-141

The KDG SIDELOK Cantilever Scope Ring Mount Modular Kit in 34mm represents a thoughtful approach to mounting optics on modern rifles and carbines. Built on the proven SIDELOK quick-detach platform, this modular system combines tool-free convenience with the flexibility to swap optics and rings without replacing the entire base. It's designed for shooters who run different optics across multiple platforms, or who want a mount that grows with their setup rather than forcing them to start over.

What sets this cantilever mount apart is its modular architecture. The removable cantilever bar runs parallel to the bore, making it ideal for semi-automatic and fully automatic carbines, rifles, and DM-pattern firearms. The matched front and rear rings are CNC machined and wire EDM cut for concentricity, with witness marks that help you align them correctly every time. The ring adjustment track system lets you slide the rings forward or backward to clear large objective bells, turret knobs, or magnification collars—a practical feature that eliminates guesswork and fitment headaches. If you upgrade to a different optic tube diameter down the road, you can simply purchase new rings and keep the base, saving significant money compared to buying an entirely new mount.

The 34mm tube diameter accommodates premium, heavy-duty optics common in long-range and tactical applications. Type 3 hardcoat anodizing in black provides the durability and low-glare finish expected of KDG's build quality. This is a mount for serious shooters who value precision, modularity, and the ability to adapt their gear without constant financial reinvestment.

Frequently Asked Questions

What firearms is this 34mm cantilever scope mount compatible with?

The KDG SIDELOK is designed for semi-automatic and fully automatic carbines, rifles, and DM (designated marksman) pattern firearms. The cantilever bar geometry makes it particularly suitable for modern platform rifles.

Can I adjust where the rings sit on the mount?

Yes. The rings mount to a track system that allows you to slide them forward or backward along the cantilever bar. This adjustment prevents interference with large objective bells, turret knobs, and magnification adjustment collars, and lets you dial in the optimal eye relief for your optic.

What makes this mount modular?

The rings bolt into a removable track system separate from the base. If you later switch to an optic with a different tube diameter, you can purchase a new set of rings matched to that diameter and install them on the same base. You keep the most expensive component—the cantilever base—and only replace the rings, saving significant cost compared to buying an entirely new mount.

How do I ensure the rings are aligned correctly?

The matched front and rear rings feature witness marks in the form of recessed dots. These marks help you identify and align the proper ring to its base during assembly, ensuring the mount is as precisely aligned as possible.
