Sightmark Tactical Cantilever 34mm Fixed Mount, Matte Finish

The Sightmark Tactical Cantilever 34mm Fixed Mount is a one-piece scope base and ring combination built for shooters running 34mm optics on rifles where a cantilever design fits your setup. This fixed mount positions your scope forward of the receiver, a geometry that works well for longer eye relief or when you need the optic extended ahead of your charging handle or dust cover. The matte finish blends with tactical-style builds and won't throw reflections downrange.

Cantilever mounts appeal to hunters and shooters who either prefer the sight picture geometry or need to clear an obstructed receiver. Since this is a fixed mount—not adjustable—you're relying on your rifle's zero to stay put once it's set. That simplicity can be an asset: fewer moving parts, nothing to shift under recoil if installed correctly. Pair this with a quality 34mm scope and you've got a straightforward, no-frills mounting solution.

The combo design—base and rings in one piece—means you're buying a complete mount rather than sourcing parts separately. That can save time at the workbench, though it also means the whole assembly needs to suit your rifle and optic before you commit. Double-check compatibility with your platform and tube diameter before ordering, and don't skip proper torque specs during installation.

Frequently Asked Questions

What does a cantilever mount do?

A cantilever design extends the scope forward of the receiver, positioning the rings beyond the rear of the receiver bridge. This geometry provides longer eye relief and clears obstructions like charging handles, making it useful on some platforms or for shooters who prefer that sight picture.

Is this mount adjustable?

No. This is a fixed mount, meaning once it's installed and zeroed, the relationship between the mount and your rifle doesn't change. There are no elevation or windage adjustments built into the mount itself—you'll dial your scope instead.

What size scope tube does this fit?

This mount is designed for 34mm optic tubes. Make sure your scope has a 34mm main tube diameter before ordering.

Do I need anything else to install this?

You'll need the correct screws or fasteners to attach the base to your rifle, proper alignment tools, and a torque wrench set to the manufacturer's specifications. Since this is a cantilever design, be especially careful that the mounting surface and rings are aligned correctly.
