Ncstar Comp Air Scope 4x20

The NCSTAR Compensator Air Scope 4x20 is a fixed-power optical solution purpose-built for air gun and crossbow platforms requiring precision accuracy at extended distances. The 4x magnification paired with a 20mm objective lens delivers a straightforward sight picture optimized for mid-range engagement on pneumatic rifles and crossbows equipped with 3/8" dovetail mounts—a standard interface found across most air gun and crossbow platforms.

Multi-coated optics reduce light reflection and glare while improving contrast and brightness transmission. The compact form factor—measuring 9.5 inches in length and weighing just 0.31 pounds—keeps overall sight radius minimal, preserving the agility and balance of lighter air gun platforms. The scope ships with matched 3/8" dovetail rings, eliminating compatibility guesswork and allowing immediate deployment on compatible air rifles and crossbows. Fixed 4x magnification removes the mechanical complexity of variable zoom systems, which can introduce parallax shift and reduce optical clarity in the mid-power range where air gun ballistics operate most effectively.

This scope is ideal for shooters ranging from entry-level air gun users to experienced practitioners seeking reliable glass for target work, small-game hunting, and field training. The 4x20 configuration strikes a practical balance between magnification power and field of view—adequate magnification for accurate shot placement beyond 30 yards without the tunnel vision associated with higher powers. For air gun enthusiasts who value repeatability over variable magnification, the NCSTAR 4x20 delivers straightforward performance without unnecessary mechanical systems.
