Overview
A first focal plane rifle scope built for precision shooters running semi-automatic platforms, with 4-16x magnification, a 42mm objective and a 34mm main tube.
Because the reticle sits in the first focal plane, holdovers stay accurate at any magnification setting rather than only at one fixed power. ZeroHold technology is meant to let you return to a saved zero quickly and also dial below it, which matters for shooters making rapid elevation changes mid string.
- 4-16x42mm first focal plane
- 34mm main tube, .1 MRAD clicks
- ZeroHold return-to-zero
- Illuminated Horus Tremor3 reticle
Who it's for
Built for long range precision shooters who need a scope that keeps pace with semi-auto rifles in variable light. Casual plinkers or hunters who rarely dial elevation likely won't use most of what it offers.
Pros and cons
- First focal plane reticle keeps holdovers accurate at any zoom
- ZeroHold lets you return to a saved zero and dial below it
- Compact 12.6 inch overall length for a 4-16x scope
- Illuminated Horus Tremor3 reticle built for wind calls
- No customer rating or review data available
- 34mm tube and F1 optics require compatible rings and mounts
Performance notes
Extra-low dispersion glass is aimed at maintaining color fidelity and resolution across the zoom range, while the .1 MRAD click turrets and internal adjustment range of 89 MOA elevation and 60 MOA windage give room for long range corrections. Eye relief is listed at 3.5 inches, with field of view narrowing from 26.9 feet at 4x to 6.9 feet at 16x per 100 yards.
