Vector Optics X-ACCU 1″ (25.4 mm) Low-Profile Picatinny Scope Rings, 30 mm Tube (V-40) — Ultra-stable, Lightweight, and Built for Perfect Cheek-Weld

The Vector Optics X-ACCU V-40 Low-Profile Picatinny Rings provide a robust, lightweight foundation for 30 mm tube riflescopes on any quality MIL-STD-1913 Picatinny rail. With a true 1.0″ (25.4 mm) center height from rail to optical center, these rings seat your optic close to the bore for a consistent cheek-weld, faster target acquisition, and improved ballistic trajectory alignment—especially on bolt guns, chassis rifles, and rimfire builds with adjustable combs. Precision-CNC’d from 6061-T6 aluminum, secured by a steel cross-bolt, and clamped with six Torx cap screws per ring, the V-40 rings deliver repeatable zero and dependable performance in the field or on the line.

Key Benefits & Highlights

• Low 1.0″ center height: Keeps the scope close to the bore for a natural head position, easier prone shooting, and minimized parallax error.
• 30 mm compatibility: Ideal for modern hunting optics, precision rimfire glass, and compact mid-power scopes with 30 mm tubes.
• Rigid, repeatable interface: One-piece ring bodies with a steel cross-bolt lock solidly to Picatinny rails for consistent return-to-zero.
• Even clamping, better tube protection: Six Torx screws per ring distribute pressure uniformly to reduce marring and optic creep under recoil.
• Light yet durable: 6061-T6 aluminum balances stiffness and low mass; black matte anodizing resists glare and corrosion.

Real-World Use Cases

Bolt-Action Hunting Rifles

Low rings help maintain a consistent cheek-weld with traditional stocks and minimize the need for cheek risers. The close-to-bore setup streamlines head position for quick, confident shots in the field.

Precision Rimfire & Trainer Builds

For NRL22-style courses or small-game work, a low optical axis improves stability in prone and supported positions. The steel cross-bolt and six-screw caps keep zero locked through high round counts and positional loading.

Chassis Rifles with Adjustable Combs

Set a repeatable, low sight line that pairs perfectly with adjustable cheek pieces. The compact profile increases clearance under the scope for throw levers and low-mounted bubble levels.

Mechanical Strength & Build Quality

• Body: CNC-machined 6061-T6 aluminum for alignment and rigidity.
• Rail Interface: MIL-STD-1913 Picatinny with steel cross-bolt for secure, repeatable mounting.
• Fasteners: Six Torx cap screws per ring for broad, even clamping on the 30 mm tube.
• Finish: Black matte anodized to reduce signature and improve wear resistance.

Installation Best Practices

• Prep: Degrease the rail and fasteners; lightly oil screw threads only if the torque tool specifies “wet” values.
• Align & level: Seat rings on the rail, set scope for eye relief and level the reticle; snug screws before final torque.
• Torque guidance: Keep ring cap screws ≤ 18 in-lb (≈ 2.0 N·m). Tighten in an alternating “X” pattern, maintaining even gaps left/right.
• Rail clamp torque: Cross-bolt/clamp nuts typically ~25 in-lb (acceptable up to 45 in-lb, ≈ 2.8–5.1 N·m) per manufacturer guidance.
• Witness marks: Paint-pen the screw heads to monitor any movement during heavy use or travel.
