Overview

Built for hunters who want a versatile optic without unnecessary complexity, this scope pairs a 3.5-10x magnification range with a 50mm objective for a broad field of use from predator and varmint setups to muzzleloader, slug shotgun, and longer-range applications. The second focal plane Dead-Hold BDC reticle is designed for holdover and wind drift correction, while fully multi-coated glass supports a clear sight picture. A single-piece aircraft-grade aluminum tube, argon gas purging, and O-ring seals add durability and help protect the optic from moisture, dust, and fogging. Capped, finger-adjustable turrets and the Precision-Glide Erector System round out a practical package for field use and sight-in convenience.

Pros

  • 50mm objective supports a bright sight picture for low-light hunting conditions.
  • Second Focal Plane Dead-Hold BDC reticle includes holdover and wind drift correction.
  • Fully multi-coated glass lens surfaces are designed for tack-sharp images.

  • Capped, finger-adjustable turrets allow easy return-to-zero after sighting in.

Considerations & Trade-offs

  • The 3.5-10x magnification range is versatile, but it is not a true close-quarters optic or a high-magnification long-range scope.
  • The 50mm objective can improve light gathering, but it also adds size compared with smaller-objective scopes.
  • The Second Focal Plane Dead-Hold BDC reticle keeps the reticle size constant, so holdover references are not scaled with magnification.
  • Capped turrets are practical for field use, but they are less convenient for frequent dialing than exposed target-style turrets.
