The 20 mm objective lens ensures the scope maintains a sleek and compact profile.
- Weight & Dimensions: The RS 4×20 is remarkably light, weighing only 110 grams, and has a compact length of 273 mm. Its slender 19 mm tube diameter contributes to its minimalist design.
- Recoil Tolerance: Despite its size, the scope offers adequate durability, with its recoil resistance rated for the popular .22 LR caliber, making it suitable for most low-powered PCP air rifles and spring-piston guns.
- Optimized Parallax: The parallax is factory-set (fixed) at 10 meters. This adjustment is specifically optimized for the typical close-range engagement distances of airguns and small-caliber firearms, ensuring the reticle and target remain sharp and free of parallax error at practical distances.
Features
The optic utilizes the classic Duplex reticle, a non-illuminated pattern known for its clarity and quick visibility. It comes supplied complete with ring mounts, allowing for immediate attachment and use right out of the box.
