The Stryker HD 3.5-21x44 FFP scope is designed for medium and long distance shooting. The first-class ED optics have been enclosed in a solid 44 mm tube and the durable and precise mechanics can measure even at very powerful distances. The viewfinder is equipped with the ZeroLock function which allows you to set the vertical adjustment turret lock to specific settings. The high-quality displays are tested by an impressive range of parallax adjustment, from 9m to infinity.  What makes this model unique is the fact that is has 45mm vertical adjustement.

Let's add that in this model, light transmission reaches 98% for a single layer and 92% for the entire viewfinder. The large eyepiece provides very comfortable observation. The sight is water and fog resistant, as it has been filled with nitrogen.  "The Delta Stryker HD 3.5-21x44 offers all the top-end optic features and quality. The quality of the glass and spec of the Stryker make it a true Cross-Over scope that is just as at home at the range or out in the field. Most scopes of this quality are limited to centrefire users because the minimum parallax is too far out. The Delta has a minimum parallax of 10m; meaning all shooters from airgunners to full-bore shooters can experience the top-end optics of the Delta." 

The sight is available with a single reticle in the DPRC-1 and DLR-1 focal foregrounds. The reticles offer maximum shooting comfort and great functionality throughout the viewfinder's zoom range (3.5-21x). The design of the reticles makes it possible to evaluate the distance to the object of known sizes and also to introduce a correction for the descent or elevation of the projectile's flight path and wind corrections.

The Delta Optical Stryker HD 3.5-21x44 FFP sight is available with the following reticles.
