What is the magnification range of this scope?
The scope offers a 4x to 12x variable magnification, making it suitable for both close-range and long-distance shooting applications.
What does “AO” stand for, and what is its function?
AO stands for Adjustable Objective. It allows for parallax correction from 10 yards to infinity, which ensures a sharp, focused image and improved accuracy at various distances.
What type of reticle does it have?
The scope features a Dead-Hold® BDC (MOA) reticle in the Second Focal Plane (SFP). This reticle helps minimize guesswork for holdover and windage corrections when shooting at varying ranges.
What is the benefit of Second Focal Plane (SFP)?
In an SFP scope, the reticle remains the same size throughout the magnification range. This provides a consistent aiming point and is ideal for general-purpose shooting and hunting.
Is the reticle illuminated?
No, this model does not feature an illuminated reticle. The Dead-Hold® BDC reticle is non-illuminated.
What are the lens features?
The lenses are fully multi-coated, meaning multiple anti-reflective coatings are applied on all air-to-glass surfaces. This enhances light transmission, providing bright and clear images, even in low-light conditions.
What is the eye relief distance?
The scope offers 3.9 inches of eye relief, which helps protect the shooter from recoil and ensures comfortable viewing.
What is the field of view at 100 yards?

What is the parallax setting?
Parallax is adjustable from 10 yards to infinity, thanks to the Adjustable Objective (AO), allowing for fine-tuned accuracy at any range.
