Product Overview
The GMW Green Laser Boresighter is engineered for hunters and shooters who demand speed and precision. Housed in a rugged aluminum body, the device projects a Class IIIA green laser with a maximum output of 5 mW, visible up to 150 yards in any weather condition. It comes with 32 numbered caliber adapters ranging from .17 to 12 GA, a dual‑point arbor, and two high‑capacity CR2 800 mAh batteries that provide extended operation for days of field use. The compact package (9.17 x 7.56 x 1.85 in) weighs just 381 g, making it easy to carry in a hunting pack.

Usage
Designed for both rifles and pistols, the boresighter excels in field zeroing, range practice, and quick sight checks before a hunt. Simply attach the appropriate adapter, align the green beam with your target, and make minor adjustments to your scope or iron sights. The bright green laser cuts through low light, fog, and dust, ensuring visibility at dawn or dusk. Ideal for unisex adult hunters, competitive shooters, and anyone needing a reliable zeroing tool on the go.
