Vector Optics 30 mm Adjustable Cantilever Rings for Picatinny Rail — Black

The Vector Optics adjustable cantilever rings for 30 mm tubes are a mounting solution for shooters who need to optimise eye relief and reclaim rail space without compromising structural rigidity. The adjustable height from 35 to 41 mm makes them compatible with scopes fitted with objectives of different diameters, removing the need to buy separate rings for each setup.

The cantilever geometry shifts the scope forward relative to the mounting point on the rail, delivering correct eye relief even on rifles with a short stock or when available rail space is limited. The vertical angle of the rings is continuously adjustable, allowing trajectory drop to be compensated at the mounting stage before touching the scope's turrets. This is particularly useful in long-range shooting, where every degree of pre-tilt translates directly into recovered elevation travel.

The body is machined from 6061-T6 aluminium alloy, the same material used in aeronautical construction for its balance of mechanical strength and low weight. Each ring is secured with four through-bolts that distribute clamping pressure evenly around the scope tube and provide a solid grip on Picatinny, Weaver or 11 mm dovetail rails. The anti-rotation cross-bolt prevents longitudinal shift even under repeated recoil.

Key features

• Adjustable height from 35 to 41 mm to suit objectives of different diameters without changing rings.
• Continuously adjustable vertical angle to pre-tilt the scope and maximise available elevation travel.
• Four clamping screws per ring distribute load evenly and withstand repeated recoil.
• Compatible with Picatinny, Weaver and 11 mm dovetail rails via the integrated anti-rotation pin.
• Cantilever geometry optimises eye relief and frees up rail space for additional accessories.
• CNC-machined 6061-T6 aluminium for structural strength with reduced weight.
