Vector Optics 30mm One-Piece Extended Picatinny AR Mount (V-18 / XASR-3031) — Neutral 0 MOA, Black Matte, Cantilevered Precision for AR-15/AR-10

The Vector Optics V-18 30mm One-Piece Extended Picatinny AR Mount is a rugged, cantilevered monoblock designed to place your LPVO or mid-power scope exactly where it belongs on flat-top AR receivers. A neutral 0 MOA base keeps your optic near mechanical center for common 50–200 m zeros, while the 38 mm (1.5") optical center height delivers a natural, heads-up shooting posture and comfortable cheek weld. Precision-machined from 6061-T6 aluminum and finished in a durable black matte anodizing, the V-18 provides a stable, repeatable interface with dual clamp nuts and four cap screws per ring to hold zero through recoil and hard use.

Key Features & Advantages

• Neutral 0 MOA base: Keeps your scope’s elevation close to mechanical center for predictable tracking and clean holds from 0 to mid-range distances.
• Cantilevered one-piece body: Pushes the optic forward for ideal eye relief with LPVOs (1–6× / 1–8×) and mid-range scopes (2–10× / 3–15×).
• AR-friendly height: 38 mm (1.5") bottom-to-center height clears common 24–50 mm objectives and supports heads-up target acquisition.
• Monoblock rigidity: One piece equals better alignment, stronger return-to-zero, and fewer failure points than two separate rings.
• Even clamping: Four cap screws per ring distribute pressure across your 30 mm tube to minimize marring and slippage.
• Secure rail interface: Dual clamp nuts with steel cross-bolts bite firmly onto MIL-STD-1913 Picatinny rails for repeatable mounting.
• Durable black matte finish: Low-glare, corrosion-resistant surface suitable for hunting, training, and competition.

Real-World Use Cases

General-Purpose LPVO Carbine

The V-18’s forward offset sets LPVO eyepieces where they run fastest for both-eyes-open work. The 0 MOA deck makes it simple to confirm a 50/200 m zero without eating up turret travel.

Hunting & Field Rifles

Stable, even ring pressure helps maintain zero across temperature swings and rough carry. The 1.5″ center height pairs well with helmets, caps, and ear-pro for a consistent cheek weld in the field.

Training & High Round Count

One-piece stiffness plus dual clamp nuts resist shift from barricade pressure and repeated recoil cycles, reducing variables during classes and practice.

Mechanical Strength & Protection

• Material: 6061-T6 aluminum alloy, full-CNC machined for stiffness and ring concentricity.
• Finish: Black matte anodizing for durability and reduced signature.
• Rail interface: MIL-STD-1913 Picatinny; extended footprint for secure clamping and alignment.
• Torque guidance: Ring cap screws ≤ 18 in-lb; clamp nuts typically 25 in-lb (acceptable up to 45 in-lb). Tighten evenly in an alternating pattern with a calibrated torque tool.
• Designed for hard use: Monoblock design maintains zero under recoil and positional loading.

Technical Specifications

Installation Notes (Best Practice)

• Degrease rail and hardware; seat the mount square on the Picatinny rail and snug both clamp nuts evenly before final torque.
• Level rifle and scope; tighten ring caps in an alternating “X” pattern to spec, maintaining even left/right gaps.
• Use minimal non-permanent thread treatment only if required. Follow your torque driver’s “dry” vs “wet” values.
• Add paint-pen witness marks on screws for fast visual checks during training or field use.

Summary

The Vector Optics V-18 30mm One-Piece Extended AR Mount is a dependable, black-anodized foundation for LPVOs and mid-power scopes on AR platforms. Its 0 MOA base, 1.5" center height, and cantilevered geometry deliver correct eye relief and consistent zero, while the one-piece 6061-T6 construction and dual clamp nuts keep everything locked down through recoil, training, and real-world use.
