The Delta Stryker HD 5-50x56 SFP (often referred to by users as the 10-50 class) is a high-performance, second focal plane (SFP) rifle scope designed primarily for long-range target shooting, F-Class, and bench rest competitions. Manufactured in Japan by Light Optics Works, it is widely regarded as offering "tier-one" optical quality at a significantly more accessible price point than many competitors.

 

Key Specifications & Performance. 

 

• Magnification & Glass: Features a 10x zoom range (5-50x) using high-quality ED (Extra-low Dispersion) glass. While clarity is excellent across most of the range, some light drop-off and a shallow depth of field can be noticed at the maximum 50x setting.
• Precision Turrets: Equipped with large, exposed tactical turrets featuring a ZeroLock mechanism. Depending on the model, click values are either 0.05 MRAD (for DLS-1/DLS-2 reticles) or 1/8 MOA (for the DLS-3 reticle).
• Physical Build: Built on a robust 34mm main tube, the scope is 100% waterproof and nitrogen-purged. It is relatively heavy at 1,060–1,100 grams but fairly compact (approx. 363–398mm long) for its power range.
• Parallax Adjustment: Side focus adjusts from 10 metres to infinity, making it highly versatile for everything from close-range airgun shooting to extreme long-range tasks.
