Kronos Airsoft reviews the Nuprol ZR10 Optic recommend for use with airsoft sniper rifle with 1.25-5x26 magnification. The dials for windage and elevation are adjustable and can be locked to keep the settings in place. It is illuminated with 3 colours to choose from and variable brightness... "Could this be the best airsoft optic you can buy? not only could this be used as a sniper scope it can also be used on a mid-long rifle."
