I have a pentax 4 x 16 which also got for a good price. It has the ballistic recticle on it. Only thing I can say negative about it is at distances less than 100 yds I have a severe paralax problem. I found this out when I could wait to shoot my 223 that I mounted it on, and shot it at an indoor 50 yd range. Either I could get the target in focus, or the cross hairs in focus by using the ocular adjustment. It does not have a paralax adjustment on it.
Once I was able to shoot at 100 yds, no big deal.
