12 Gauge Laser Bore Sighter

Features

1. 12 Gauge Chamber Fit — Drops directly into any standard 12 gauge shotgun chamber for fast, no-tools zeroing of red dots, scopes, and bead sights.
2. Red Laser Output — Class IIIa red laser at 635–655nm with less than 5mW output delivers a bright, clearly visible aiming dot in low light and indoors.
3. Factory Pre-Aligned — Each cartridge is pre-aligned at the factory so the laser projects true to bore axis right out of the package.
4. Hard Anodized Aluminum Body — Machined aluminum construction with a hard anodized finish stands up to repeated chambering and field use.
5. Compact Cartridge Dimensions — Measures roughly 2.4 inches long and weighs about 1.7 oz with batteries installed, keeping it pocket-friendly for the range or blind.
6. Simple Battery Activation — Install the included batteries and thread on the base cap to power the laser; remove the batteries to shut it off — no switches to fail.
7. Slug Gun Ready — Ideal for zeroing rifled slug barrels and scoped deer guns where conventional bore sighting tools won't fit.
8. Self-Contained Unit — No adapters, arbors, or extra accessories required — the cartridge is the complete tool.
9. Saves Ammo at the Range — Get on paper before firing a shot, cutting down on expensive shells and live-fire walk-in time.
