Vector Optics ViperRay 12 Gauge Cartridge Red Laser Bore Sight (SCBCR-02) — Fast, repeatable pre-zero for 12 GA shotguns

The Vector Optics ViperRay 12 Gauge Cartridge Red Laser Bore Sight helps you align beads, ghost-ring sights, or red-dot optics in minutes—before firing a single shell. Machined from brass to the geometry of a real 12 GA shell, it projects a 650 nm red Class IIIA (<5 mW) laser precisely along the bore axis. Rough-in your point of aim at home or at the bench, then confirm at the range with a handful of slugs or pattern shots. This simple workflow saves time, reduces ammunition use, and gives you confidence that your setup survived travel and hard use.

The cartridge-accurate body chambers concentrically for a stable, repeatable reference, and each unit is factory pre-centered so you can work quickly. Despite its robust construction, the tool remains compact—just 61 mm (2.4″) long and 130 g (4.6 oz)—so it lives easily in your range kit for zero checks and sight installs.

Real-World Use Cases

Slug zeroing (deer, boar, practical matches)

Use the bore-axis laser to align your red dot or rifle-style sights for 50–100 m slug work. You’ll arrive at the range already “on paper,” then fine-tune with a few confirmation shots.

Turkey & upland pattern work

Bring point-of-aim closer to the center of your pattern before stepping to the board. This reduces shell count when validating different chokes and loads.

Home defense & competition shotguns

After transport or a hard training block, chamber the ViperRay to verify zero on a fixed indoor reference in seconds—especially helpful with optics or adjustable rifle sights.

Mechanical & Build Highlights

• Cartridge-accurate geometry: Brass shell mirrors 12 GA case dimensions for concentric seating and repeatable alignment.
• Bright reference point: 650 nm red dot provides a clear, high-contrast aim mark for fast coarse alignment under typical indoor lighting.
• Factory-centered emitter: Pre-set alignment minimizes setup time and user error.
• Compact & durable: Robust construction stands up to frequent chambering during installs, service, and checks.

What’s in the Box

• ViperRay 12 GA cartridge red laser bore sight (SCBCR-02)
• User instructions
• Batteries not included (requires 3 × AG13 button cells)

Compatibility & Setup Notes

• Chambering: For 12 Gauge chambers only. Do not use in 20 GA, 16 GA, or other gauges.
• Safety first: Verify the shotgun is unloaded, magazine and chamber clear. Keep the muzzle in a safe direction; do not look into the beam.
• Initial alignment: Choose a small indoor reference mark (5–10 m). Adjust your bead/ghost-ring or optic until point-of-aim coincides with the laser dot.
• Finalize at the range: The laser travels straight while slugs and shot patterns follow a trajectory. Always confirm and refine with your actual load and choke at your working distance.
• Battery tips: Insert three AG13 cells with correct polarity; remove between uses to prevent drain.
