Overview
The Diamondback HP 4-16x42 is a second focal plane riflescope built on a 1 inch tube with extra-low dispersion glass and a Dead-Hold BDC reticle for holdover reference at varying ranges. Side focus parallax adjustment and finger-adjustable, zero-resettable turrets are built into the housing.
Because this is a second focal plane scope, the Dead-Hold BDC holdover marks are calibrated to a specific magnification rather than scaling automatically as you zoom, which is standard for hunting scopes at this price point.
- 4-16x42 second focal plane scope
- Dead-Hold BDC reticle
- Side focus parallax adjustment
- Nitrogen purged, waterproof and fogproof
Who it's for
Hunters and range shooters who want a rugged, waterproof and fogproof scope with holdover reference and Vortex's warranty behind it. Not the choice for shooters who specifically want a first focal plane scope where reticle subtensions scale with zoom.
Pros and cons
- Turrets reset to zero after sighting in
- Vortex's warranty cited repeatedly by owners
- BDC holdover marks calibrated to a fixed magnification
Performance notes
Extra-low dispersion glass and XR fully multi-coated lenses are built to raise light transmission and clarity across the 4x zoom range. Nitrogen purging with o-ring seals is meant to keep the scope waterproof and fogproof, and the housing is built shockproof for recoil. Side focus lets parallax be dialed from the shooting position rather than at the objective bell.
