EZshoot Green Laser Bore Sighter Kit .17–12GA — 16 Adapters & Big Button Switch

EZshoot Bore Sight Laser Kit is a compact green-laser alignment tool that fits .17 through 12 gauge firearms using 16 adapters and a stabilizing arbor for quick, accurate sighting. The EZshoot kit pairs a vivid green laser with a robust metal housing and a large tactile switch so you can zero optics or iron sights faster and with less trial-and-error. Designed for field and range use, the unit runs on an upgraded CR2 battery and ships with adapters to cover a wide range of calibers, plus tools and a short guide to get you started without guesswork.

How visible is the green laser in daylight and low light?

The bright green laser is easier for the human eye to detect than a red beam, improving visibility across variable lighting. While any laser appears brighter in dim conditions, this green output was chosen to remain useful in partial daylight for short-to-moderate distances.

• Max output: under 5 mW (Class IIIa) for range-appropriate visibility
• Clear, concentrated beam designed to resist light scatter
• Works best for aligning sights at typical zeroing distances

Which calibers and adapters are included, and how do I select the right one?

The kit includes 16 size adapters plus one arbor to stabilize the assembly, covering bore sizes from .17 to 12 gauge. Match the adapter to your bore diameter and insert the arbor if your caliber falls within the arbor’s specified range to keep the laser centered and secure.

• Adapter set fits .17 up to 12GA firearms
• Arbor fits calibers approximately .54 to .79 inches (#10–#16)
• Choose the snug adapter for a centered, wobble-free fit

How do I operate the unit and manage power?

Operation is straightforward: install the supplied CR2 battery, select the correct adapter, insert the bore sight, and press the oversized button to toggle the laser. The larger switch provides reliable tactile feedback even with gloves, and the upgraded CR2 offers extended runtime compared with smaller cells.

• Uses one CR2 battery (included) for long service life
• Big, responsive button switch for easy ON/OFF control
• Simple assembly with included tools and instructions

Is the bore sighter durable enough for range and field use?

The housing uses a metal construction and precision assembly to resist wear from repeated use and handling. Its compact footprint and solid build mean it stores easily in a range bag and stands up to normal range routines.

• Sturdy metal structure for long-term reliability
• Compact design for easy transport and storage
• Comes with tools and a protective case for safe carrying

Who is this for This EZshoot Bore Sight Laser Kit is made for shooters, hunters, and gunsmiths who want a fast, repeatable way to align scopes or iron sights without trial-and-error live firing.
