OPTICS GUIDES

UNDERSTANDING RIFLESCOPE SPECIFICATIONS

Riflescope specifications can look complicated at first. The key is to understand what each number describes and how the specifications relate to the way an optic is intended to be used.

MAGNIFICATION

A specification such as 3-15x describes a variable magnification range. The first number is the lowest magnification and the second is the highest. A wider range provides more flexibility, while the appropriate range depends on the intended application and viewing conditions.

OBJECTIVE SIZE

The objective diameter, such as 44mm or 56mm, describes the front lens diameter. Larger objectives can support light transmission and image brightness, but they can also increase the overall size and weight of an optic.

FIRST VS SECOND FOCAL PLANE

In a first focal plane (FFP) scope, the reticle changes apparent size as magnification changes. In a second focal plane (SFP) scope, the reticle remains the same apparent size. The choice depends on the product design and the user's preference.

TUBE DIAMETER

Main tube sizes such as 30mm and 34mm describe the diameter of the scope's main tube. Compatibility with appropriate mounts and rings should always be checked against the exact product specification.

RETICLE

Reticle designs vary significantly between models and variants. When comparing products, check the exact reticle listed for the specific model rather than assuming that every version of a product uses the same configuration.

HOW TO COMPARE OPTICS

Start with the exact model, then compare magnification, objective diameter, focal-plane configuration, tube diameter, reticle and physical dimensions. Also confirm availability, included accessories and any warranty information before ordering.
