The ideal first air rifle scope

The SMK 4×20 Air Rifle Scope is a great starting point for juniors and beginners moving up from open sights. With a fixed 4x magnification and 20mm objective, it keeps things simple: there are no magnification settings to fiddle with, just a clear, steady sight picture that helps new shooters learn the fundamentals of aim and accuracy.

Clear optics for plinking and targets

Despite its budget-friendly price, the 4×20 delivers a bright, clear view for close-range shooting. It is well suited to plinking and target practice, with useful accuracy out to around 20 yards, making it a genuine upgrade over iron sights for backyard and range use.

Mounts included and ready to fit

The scope comes complete with standard 11mm dovetail mounts, so there is nothing else to buy to get shooting. The 11mm (3/8 inch) dovetail is the traditional rail found on most air rifles, and the mounts line up easily for a quick, fuss-free fit.

Compact, light and dependable

The compact 19mm tube and lightweight build make the 4×20 a natural match for smaller airguns and junior rifles, keeping the balance comfortable. For more air rifle scopes, pellets and accessories, browse our outdoor shooting range.
