If choosing a pellet rifle scope seems like a complicated mission to you, you’ve come to the right place! There are dozens of models with different features. To guide you in your choice, we review the important criteria to take into account in this choice Airsoft.
Before getting to the heart of the matter, let’s start with the basics. When we talk about a 3-9 x 40 riflescope what does that mean? The first number 3 represents the minimum image magnification of the telescope and the number 9 corresponds to the maximum zoom. The number 40 corresponds to the diameter of the objective (lens on the target side).
THE ZOOM
Zoom is one of the first criteria to look at. This data corresponds to the magnification of the image in the telescope. The zoom of a scope can be fixed, for example a 4 x 32 scope, or variable, for example a 3-9 x 40 scope. To determine the ideal zoom level, you need to know the distance you want to shoot at. .
A compressed air rifle of 20 joules or more allows you to carry out shooting sessions over a long distance. In this case, choose a riflescope with at least a 4x zoom, which is the standard for a pellet rifle. If you shoot at a distance greater than 35 meters, for better visual comfort, choose a magnification of 6 x or 9 x. Such a large zoom results in an image that is more susceptible to shake. To minimize this effect, opt for a stable shooting position (on a table or support). This way, you will be able to fully exploit the precision of your optics.
LENS DIAMETER
As a reminder, the diameter of the lens of the riflescope corresponds to the number after the X. This characteristic has a direct impact on the light transmission in the lens. Larger lens size provides better brightness.
When choosing a riflescope, the quality of the lenses is also of great importance. The lenses receive surface treatments to improve image sharpness. Indeed, not all brands are equal. They do not all use the same treatment processes. This explains why certain glasses with similar characteristics can have a significant difference in price.
As an idea, a standard 20 joule air rifle can shoot accurately out to 25 yards. For this type of compressed air weapon, choose a riflescope with an aperture of 32 mm.
For a powerful pellet or PCP rifle, a lens of at least 40mm or 50mm seems the most appropriate choice. Indeed, for shooting at a distance between 30 and 75 meters, this type of optical sight offers an image with excellent definition.
