This is the new version of the Delta Optical Stryker HD 3.5-21x44 FFP scope.
For years, Delta Optical has been helping ambitious shooters achieve their dreams and passions. An expression of this is our unique and most advanced range of Stryker HD precision scopes. The scopes in this series are characterized by their construction based on ED glass, which guarantees excellent image quality and high light transmission, special anti-reflective coatings, and an illuminated central dot that allows shooting even in low-light conditions.
The Stryker HD 3.5-21x44 FFP scope was designed for medium and long-distance shooting. The first-class ED optics are enclosed in a solid 44 mm tube, and the durable and precise mechanics can handle even very powerful distances. The scope is equipped with the ZeroLock function, which allows you to set the lock of the vertical adjustment turret for specific settings. The high-quality scopes are tested with an impressive parallax adjustment range, from 9 m to infinity.
Let us add that in this model, light transmission reaches 98% for a single layer and 92% for the entire scope. The large eyepiece provides very comfortable observation. The scope is waterproof and fog-proof, as it has been filled with nitrogen, and it also allows you to adjust the aiming reticle up to 300 cm vertically.
The scope is available with a single reticle in the first focal plane, DPRC-1 and DLR-1. The reticles offer maximum shooting comfort and great functionality across the entire zoom range of the scope (3.5-21x). The design of the reticles allows you to estimate the distance to an object of known size and also to apply corrections for the drop or elevation of the projectile’s trajectory and wind corrections.
The Delta Optical Stryker HD 3.5-21x44 FFP scope is available with the following reticles
· DPRC-1 - ref: DO-2514
· DLR-1 - ref: DO-2515
DLR-1 Reticle
The DLR-1 reticle includes an illuminated central dot with a diameter of 0.07 mrad and thin arms with transparent segments 0.4 mrad thick. The arms are divided with markers every 0.2/0.5/1 mrad, allowing you to accurately estimate the distance to an object of known size and make corrections for the drop or elevation of the bullet’s flight path and wind corrections. The DLR-1 reticle was designed specifically to operate in the first focal plane (FFP) and to maintain constant dimensions relative to the target across the entire magnification range. In addition, the grid is scaled in milliradians, making conversion to metric units easier (1 milliradian = 10 cm at 100 m).
