Vector Optics 30 mm 20 MOA One-Piece Mount — Black

One-piece mount in 6063-T6 aluminium for 30 mm tubes, designed to fit precision riflescopes on Picatinny rails with an integrated cant compensation of 20 MOA. The monolithic construction holds the two rings at a 57 mm centre-to-centre spacing and places the optical centreline at 35 mm above the rail base, compatible with most cheekpieces and bench-rest setups. The overall length of 146 mm and a modest weight of 150 g make it suitable for both hunting configurations and precision rifles.

The 20 MOA compensation built into the base is not merely a cosmetic offset: it allows the riflescope's elevation adjustment to start partially wound down, recovering the full usable travel of the reticle for long-range corrections. On optics with a limited total elevation range, this additional margin can make the difference between reaching or missing the point of aim at 500–800 m without resorting to shimmed bases or separate angled mounts. The skeletonized profile removes non-structural material whilst retaining the torsional stiffness needed to withstand repeated recoil: the 3 cross-bolts on the rail and the 6 ring screws distribute the load across multiple contact points, reducing the risk of clamp failure even under sustained stress.

A one-piece mount eliminates the misalignment between front and rear rings that can occur when pairing two separate rings on rails that are not perfectly flat, but it requires the optic to be inserted horizontally from one end: anyone fitting riflescopes with large-diameter eyepiece housings or fixed sunshades should verify compatibility before installation. The matt black finish reduces reflections in lateral lighting conditions. No tools are included in the box.

Key features

• The integrated 20 MOA compensation returns usable elevation travel to the optic, allowing long-range corrections without shims or additional bases.
• The monolithic 6063-T6 aluminium construction maintains ring alignment from one shooting session to the next, with no recoil-induced shift.
• The optical centreline height of 35 mm above the base is compatible with most standard scope mounts and with a natural shooting position on rifles with a conventional comb.
• The clamping system with 3 cross-bolts on the rail and 6 ring screws spreads the load across multiple points, reducing the risk of slippage under repeated recoil.
• The lightweight (skeletonized) profile brings the total weight to 150 g, keeping bulk to a minimum without compromising structural rigidity.
