Zerotech Trace ADV 4.5-27x50 RMG Scope The Zerotech Trace ADV 4.5-27x50 RMG rifle scope is specially made for sport shooting, but it performs well for those hunters who are fond of the most extreme stalking. With its tactical-sports orientation, it has a corresponding first focal plane (FFP) reticle. It is a robust rifle scope with a 30 mm aeronautical aluminum tube. Matte black finish. The use of O-rings and argon gas purging make it completely waterproof and fog-proof. Regarding the optics, this rifle scope uses high quality glass, the lenses being equipped with complete coatings that guarantee a light transmission of 92%. The images obtained are bright, sharp and clear, with good performance in low light conditions. To preserve the lenses, those that are in contact with the outside, have a proprietary coating to protect against scratches and abrasions. Something logical being a scope designed to operate in a country as sandy and dusty as Australia. The turrets use the so-called Precision Turret System (PTS), proprietary from ZeroTech. These are visible and oversized, as befits a sports-oriented visor. They have a locking system that means that they can only be adjusted by previously pulling them, pushing towards the body of the viewer, they are locked. The lifting turret has a simple zero stop system, using a small 1.5 mm Allen key. As for the operation of the turrets, they have a crisp, audible click, with just the right balance of hardness and sensitivity to make them quick and easy to use. Scaled in MILs, each click corresponds to 0.1 MILs, or a variation of one centimetre at 100m. The maximum correction range on elevation is 17.5 MILs and on drift is 16 MILs. On the opposite side of the latter turret is the parallax adjustment control, which is surprising in that its starting point in its configuration is only 25m at infinity. A feature that will be appreciated by those who use the scope with percussion rifles. The RMG reticle allows shooters to apply elevation and wind variations without having to use the turrets. Subtended in 0.5 MIL increments with integrated 0.1 MIL gauge bars. A floating center point ensures a refined aiming point for zeroing and good shot groupings, while thicker bars with chevron ends at 3, 6, 9 and 12 o'clock help draw the shooter's attention to the center of the reticle at lower magnifications. In a market as competitive as the current one, its assets are an exceptional quality-price ratio, accompanied by a foolproof robustness and several interesting technological innovations.   Features Zerotech Trace ADV 4.5-27x50 RMG rifle scope · Power x Objective diameter (mm.): 4.5-27x50 · Finish: Matte · Tube: 30mm. · Reticle: RMG · Field of view (m.
