This sight is an optical aiming device with specific performance and characteristics. "1-6X" indicates a magnification range of 1 to 6 times, "24" represents an objective lens diameter of 24 millimeters, and "SFP" refers to the reticle being located at the second focal plane. Here is its product introduction:
Main features
Second focal plane design: The reticle is located on the second focal plane, and the size of the reticle scale does not change with the magnification. Under different magnifications, the visual effect of the reticle remains consistent, making it simpler and more intuitive for users who do not need to precisely calculate ballistic holdover.
Variable magnification function: With a variable magnification range of 1-6 times, it can provide a wide field of view at 1x magnification, facilitating the rapid capture of close-range targets, suitable for scenarios such as close combat. At 6x magnification, it can also provide more precise aiming for medium-range targets, meeting shooting needs at different distances.
Good optical performance: Typically, multi-layer coated lenses are used, which can effectively reduce light reflection and increase light transmittance, thus providing clear and bright images, even in dimly lit environments.
The reticle design is diverse: the sight adopts a simple circular dot reticle, and features a red illumination function with multiple illumination brightness levels, making it convenient to use under different lighting conditions.
Durable and Robust: Made of 6061-T6 aviation-grade aluminum alloy, it boasts excellent strength and corrosion resistance. The lens barrel, with a diameter of 30mm, offers a certain degree of internal adjustment range and high durability. Additionally, it features waterproof, dustproof, and anti-fog capabilities, achieved through O-ring sealing and nitrogen filling. After rigorous factory testing, it possesses high shock resistance.
Tactical application: 1x magnification is suitable for close-range combat, allowing for quick target acquisition, while 6x magnification can be used for precise aiming at medium distances, making it ideal for tactical carbines and other weapons used in combat scenarios at medium to close ranges.
Hunting: In environments such as forests, low magnification allows for quick observation of the surrounding environment and prey movements. In more open areas, 6x magnification can meet the needs for reconnaissance and aiming at medium-distance prey, making it suitable for various hunting scenarios.
Shooting sports: For some shooting competition events involving medium and close ranges, the performance and characteristics of the sight can meet the requirements of shooters for rapid aiming and precise shooting.
