Overview

Built for shooters getting into PRS or looking for a capable first precision optic, this scope combines a 10-40x56mm configuration with a second focal plane BLR MOA reticle for deliberate target work at distance. The 4x magnification range gives it flexibility across multiple shooting disciplines, while the Precision True Zero Stop is a practical feature for dialing and returning to a known setting. Advanced fully multi-coated optics are described as providing a bright, clear image in low light, and the XPL coating adds protection for the lenses in dirt, grease, and harsh weather. It is a straightforward option for range use and precision shooting, with the trade-off of being more specialized than a general-purpose hunting scope.

  • XPL coating helps protect lenses from dirt, grease, and harsh weather.

Considerations & Trade-offs

  • The 10-40x magnification range is geared toward precision work, so it is less suited to close-range or fast-moving hunting scenarios than lower-power optics.
  • As a second focal plane scope, reticle subtension is not constant across all magnification settings, which is a consideration for shooters who prefer holdovers at varying power levels.
  • The 56mm objective supports a bright image, but it also adds size and weight compared with more compact hunting scopes.
  • This model is positioned for PRS and precision shooting, so hunters looking for a simpler field scope may find some of its features more than they need.
