Vector Optics ViperRay .223 Rem Cartridge Red Laser Bore Sight (SCBCR-03) — Fast, ammo-saving pre-zero for .223/5.56 rifles

The Vector Optics ViperRay .223 Rem Cartridge Red Laser Bore Sight is a caliber-specific, chamber-insert collimator that gets your optic on paper in minutes. Precision-machined from brass to mirror a real cartridge, it projects a bright 650 nm Class IIIA (<5 mW) red laser from the bore axis, so you can align your riflescope, prism, or red dot at home or on the bench. It’s purpose-built for .223 Rem / 5.56 mm NATO chambers, delivering reliable concentric seating and a repeatable reference point before you confirm zero with live fire.

Key Parameters

• Caliber: .223 Remington / 5.56 mm NATO (cartridge-style chamber insert)

• Dimensions & Weight: 44.5 mm (1.8″) length; 11 g (0.4 oz)
• Body: Brass housing for durability and consistent fit
• Power: 3 × AG3 (LR41) button cells
• Model / SKU: SCBCR-03 (ViperRay series)

Real-World Use Cases

New optics, bases, or ring installs

Rough-in a fresh scope or red dot on a fixed indoor reference. Arrive at the range already on paper and use only a handful of rounds to finalize a precise zero.

Post-transport & seasonal checks

Travel, temperature swings, or hard training can nudge mounts. Chamber the ViperRay to verify your reticle still overlays a known reference point before burning ammo on groups.

Shared-optic workflows

If you rotate optics between .223/5.56 rifles, this cartridge-accurate insert helps you re-index quickly and consistently, speeding platform changes and conserving ammunition.

Mechanical & Build Highlights

• Cartridge-accurate geometry: Brass case dimensions seat concentrically on the bore axis in .223/5.56 chambers for repeatable alignment.
• Clean, visible reference: 650 nm red dot is easy to see on typical indoor targets for fast coarse alignment.
• Factory-centered emitter: Pre-set alignment minimizes setup time and user error.
• Compact, range-bag friendly: At just 44.5 mm long and 11 g, it’s a pocket-size tool for quick verification before matches or hunts.

What’s in the Box

• ViperRay .223 Rem red laser bore sight (SCBCR-03)
• User instructions
• Batteries typically not included (most retailers ship without cells due to shipping rules; requires 3 × AG3/LR41)

Compatibility & Setup Notes

• Chambering: For .223 Rem / 5.56 mm NATO chambers only. Do not use in other .22-caliber centerfires (e.g., .222 Rem, .22-250 Rem).
• Safety first: Verify the firearm is unloaded, magazine removed, and chamber clear before inserting the bore sight. Keep the muzzle pointed in a safe direction; avoid eye exposure to the laser.
• Initial alignment: Choose a small indoor mark (5–15 m). Adjust your reticle or sight until it coincides with the laser dot.
• Finalize at the range: The laser travels in a straight line while bullets follow a ballistic arc. Always confirm and refine zero with live ammunition at your chosen distance (e.g., 50/100 m), accounting for load and sight height.
• Battery care: Observe correct polarity; remove cells between uses to prevent drain.

Technical Specifications

Summary

The ViperRay SCBCR-03 streamlines every sight-in on .223/5.56 rifles. Its brass, cartridge-accurate body and pre-centered 650 nm Class IIIA laser give you a fast, repeatable starting point—so you save time and ammunition, then lock in a precise live-fire zero with confidence.
