The Vector Optics offset cantilever mount gives you the strength and alignment you need to secure 30 mm scopes to any Picatinny rail system.
Its extended forward offset design provides proper eye relief on AR platforms and other rifles where rail space is limited, ensuring comfortable head position and full field of view.
Machined from high-grade aluminium with a matte black anodised finish, this one-piece mount offers excellent strength-to-weight balance.
The cantilever design also helps optimise scope placement for correct cheek weld and balance.
Perfect for:

AR rifles or carbines where eye relief needs extra forward positioning
-
30 mm tube scopes on Picatinny rails
-
Shooters who prefer a clean, one-piece cantilever setup for strength and alignment

Q: Why use a cantilever mount?
A: It shifts the optic forward, giving correct eye relief when rail space is limited—common on AR platforms.
Q: Will this fit 11 or 13mm dovetail rails?
A: No—this mount is only for 20-22 mm Picatinny/Weaver bases.
Q: Is it strong enough for recoiling rifles?
A: Yes—made from robust CNC-machined aluminium, it’s built to handle recoil.
Q: Does the offset affect accuracy?
A: No—once zeroed, accuracy remains the same. The offset simply corrects eye relief and positioning.
Q: What’s the difference between straight and offset cantilever mounts?
A: Straight cantilevers extend the optic forward in-line with the rail, while offset mounts push the optic further forward with an angled extension.
Q: When would I need an offset cantilever?
A: If you’re using a longer scope, or your rifle has very limited rail space, an offset version ensures you still get proper eye relief.
Q: Does the offset affect durability or zero?
A: No—quality offset mounts are just as strong and hold zero reliably.
Q: Which is more comfortable for shooting?
A: Offset mounts often allow a more natural head position, especially on ARs or carbines with compact rail systems.
