Vortex Sport Cantilever 30mm Mount
One-piece scope mount · 30 mm · 1.5 in height · 5.4 oz · $125
Cantilever mount
A one-piece mount whose rings sit forward of the rail clamp, usually about 2 in. It moves the scope forward so a thermal's short eye relief works on an AR-15's flat-top rail.

Optics it fits
Interfaces match (calculated)
The optic maker's published mounting interface meets this mount's. That says the parts connect; it does not check eye relief, the length of tube free for the rings, or barrel clearance, and no maker has named the pairing.

Tube center above the rail is calculated only when the mount maker says where its height is measured from and the optic maker states a tube diameter; each blank says which figure is missing.
