Firefield Waterproof Tactical 4-16x42mm AO IR Rifle Scope

The 4-16x42 AO Tactical IR Riflescope from Firefield is a nitrogen-filled zoom optic designed for mid-range targets. Complementing this scope's 16x maximum zoom and 1:4 zoom ratio is adjustable objective (AO) parallax correction, which can be set from 15 yd to infinity by rotating the ring on the objective bell. This scope features a Mil Dot reticle that can be illuminated in red or green using a dedicated reticle brightness side turret. The reticle illumination control has five selectable brightness settings for each color; green illumination is more visible than red in low-light conditions, but red is more useful for targeting subjects among a woodland landscape. In addition to the broad zoom range and illuminated reticle, the Tactical riflescope has a multicoated optical path, shock-resistant housing, and 1/4 MOA locking turrets, equipping this optic for reliable mid-range performance outdoors.
