Quick Answer
The green light optics that work best with .17 Remington rifles are typically 2-5x variable power scopes with a 32-40mm objective lens, featuring a 4-6mm exit pupil and a 2-3 MOA subtension. These optics provide a clear and magnified view of small varmints, such as prairie dogs and rodents, at typical shooting distances.
Choosing the Right Objective Lens Size
When selecting a green light optic for a .17 Remington rifle, the objective lens size plays a crucial role in determining the amount of light that enters the scope. For varmint hunting, a 32-40mm objective lens is ideal, as it provides a good balance between light transmission and a compact, lightweight design. A larger objective lens can be beneficial in low-light conditions, but it also increases the scope’s size and weight.
Understanding Exit Pupil and Subtension
The exit pupil of a scope is the diameter of the light beam that exits the scope, measured in millimeters. A 4-6mm exit pupil is suitable for varmint hunting, as it allows the shooter to see clearly in bright sunlight. Subtension refers to the number of minutes of angle (MOA) that a target moves when the reticle is moved one inch at the target. A 2-3 MOA subtension is typical for varmint hunting, providing a fine, precise aiming point for targeting small animals.
