Really great scope! Easy to zero for airsoft, comes with two scope mounts (25.4mm NOT 30mm) There's enough room to attach the scope to the rifle (Mine's a G&G GR25) and you can also attach a scope to RIS adaptor to attach a back micro red dot sight on top, which is a great and useful addition. Really great illumination although I haven't really used it with that option and very clear zoom/distance adjustments. Very happy with the purchase and a great service provided by ZeroOne as always!
