Why choose the Athlon Helos BTR GEN2 2-12×42

How to choose a riflescope
When you compare riflescopes, start with magnification. Lower power gives a wider view and faster target pick-up. Higher power helps at long range. Next, look at the objective lens. A bigger lens gathers more light, but it also adds weight and needs taller rings. Also check the focal plane. A first focal plane reticle keeps holdovers accurate at every power, while a second focal plane reticle stays the same size.
Finally, make sure the turrets and reticle use the same unit, either MOA or MRAD. That makes corrections quick and simple. Mount the scope in quality rings, set the eye relief before you tighten the screws, and then zero it at the distance you shoot most.
