The Best 30mm Cantilever Scope Mounts – Built for Serious Shooters
If you're running a 30mm optic on your AR-15, LPVO, or bolt-action rifle, a cantilever mount is the smart choice. Designed to position your scope forward on the rail, a cantilever mount improves eye relief, sight picture, and overall shooting ergonomics — especially when space on your upper receiver is limited.
At Mounts Plus, we offer a wide selection of 30mm cantilever mounts from trusted brands like Vortex, Bobro, Geissele, Primary Arms, and more. Whether you're looking for a lightweight fixed mount or a rugged quick-detach option with 20 MOA cant, we have the setup that fits your mission.

Why Choose a 30mm Cantilever Mount?
✅ Forward Optic Positioning
Achieve optimal eye relief and field of view, especially with LPVOs and AR-style rifles.
✅ Secure Fit on Picatinny Rails
All models are designed to fit MIL-STD-1913 rails and keep your scope locked down under recoil.
✅ Options for Every Setup
Choose from lightweight mounts, extended cantilever designs, quick-detach levers, and more.
✅ Ideal for Tactical & Precision Use
Whether you're in a 3-gun match, long-range class, or duty setup, cantilever mounts help you run faster, see clearer, and stay on target.
What Is a Cantilever Scope Mount?
A cantilever mount extends the optic forward, beyond the receiver’s rail. This lets you:
-
Mount larger scopes on shorter uppers
-
Maintain proper head position and eye box
-
Add magnifiers or backup sights behind the optic
-
Keep your balance point centered on the rifle
It’s a must-have if you're using optics like LPVOs, ACOGs, or long-tube scopes on an AR-15.

Frequently Asked Questions
Q: What’s the benefit of a cantilever mount vs standard mount?
A: Cantilever mounts extend the scope forward, giving you proper eye relief on rifles like the AR-15 with limited rail space.
Q: Will these mounts fit my 30mm LPVO scope?
A: Yes — all mounts are built for standard 30mm tube optics and will fit most LPVOs, red dot magnifiers, and variable scopes.
Q: Can I use this mount on a bolt-action rifle?
A: Absolutely — as long as you have a flat-top Picatinny rail, you can use a cantilever mount for extended eye relief.
Q: What’s the difference between 0 MOA and 20 MOA?
A: 0 MOA is for close-to-mid range use. 20 MOA is canted forward to give long-range scopes more elevation adjustment.
