What is a 30mm cantilever mount used for?

A 30mm cantilever mount positions your optic forward on a Picatinny rail to improve eye relief and maintain proper cheek weld. It's ideal for LPVOs and mid-power scopes on AR-style rifles.

Will a 30mm cantilever mount fit my AR-15?

Yes, as long as your AR-15 has a flat top Picatinny rail and your optic uses a 30mm tube, a 30mm cantilever mount will be compatible.

What's the difference between a standard and QD cantilever mount?

A quick detach (QD) cantilever mount allows for tool-free removal and reattachment of your optic, maintaining zero. Standard mounts use bolts and are better for permanent installations.

Do I need a 20 MOA cantilever mount?

You only need a 20 MOA cantilever mount if you're shooting at long distances and require additional elevation adjustment. It's ideal for precision rifles or DMR setups.

30mm Cantilever Scope Mount – Forward Mounting for Precision and Eye Relief

A high-quality 30mm cantilever mount is essential for mounting LPVOs, tactical scopes, or red dot magnifiers on an AR platform. Whether you're dialing in for precision shooting or just want consistent eye relief on a flat top rifle, the right cantilever mount gives you the forward offset and secure hold you need.

At Mounts Plus, we offer a wide range of 30mm cantilever scope mounts built for AR-15s, modern sporting rifles, and any platform that uses a standard Picatinny rail.

🔧 Why Choose a Cantilever Mount for 30mm Optics?

The cantilever design shifts the optic forward without sacrificing rail space — perfect for AR-15s where traditional ring spacing may not allow proper scope placement.

Key advantages:

🟢 Better eye relief for LPVOs and tactical scopes
🟢 Helps maintain proper shooting posture and cheek weld
🟢 Frees up rear rail space for backup sights or magnifiers
🟢 Enhances balance and sight alignment on flat top receivers

Whether you're running a 1-6x optic or a fixed-power scope, a 30mm offset mount lets you fine-tune your setup for optimal speed and precision.
