4-16x50 SFIR shooting rifle scope

The 4-16x50 SFIR shooting rifle scope is a specific type of optic designed for long-range shooting applications. Let's break down its features:

Magnification: The scope offers a variable magnification range from 4x to 16x. This means you can adjust the magnification level according to your shooting requirements. Lower magnification settings are useful for close-range or fast-moving targets, while higher magnification settings are suitable for precision shooting at longer distances.

Objective Lens: The scope has a 50mm objective lens diameter. The larger the objective lens, the more light it can gather, resulting in a brighter image with better low-light performance. A 50mm objective lens is considered relatively large and allows for good light transmission.

SFIR (Side Focus/Parallax Adjustment): SFIR stands for Side Focus/Parallax Adjustment. Parallax refers to the apparent shift in the target's position when the shooter's eye is not perfectly aligned with the scope's reticle. The SFIR feature allows you to minimize or eliminate parallax error by adjusting the focus on the side of the scope, resulting in improved accuracy.

Reticle: The specific type of reticle (crosshair) used in the 4-16x50 SFIR scope may vary depending on the manufacturer and model. Different reticle designs offer various features such as bullet drop compensation (BDC), windage marks, or ranging capabilities. Common reticle types include Mil-Dot, MOA, or BDC reticles.

Turrets: The scope may have elevation and windage adjustment turrets. These turrets allow you to make precise adjustments to compensate for bullet drop and wind drift. Some scopes feature exposed turrets, while others may have capped turrets to prevent accidental adjustments.

Construction: The construction of the scope is typically rugged and designed to withstand recoil and harsh environmental conditions. It may be made of materials like aircraft-grade aluminum or other durable alloys. Additionally, the scope may be nitrogen or argon purged to make it fogproof and waterproof.

Overall, the 4-16x50 SFIR shooting rifle scope is a versatile optic suitable for medium to long-range shooting. Its adjustable magnification, large objective lens, parallax adjustment, and other features make it useful for precision shooting, target shooting, or hunting applications where longer distances are involved.
