4.8 / 5.0
It was smacking 20 on the range with no worries. I had to bring it back to the farm for any type of hunting distance. 3 shots later I’m smacking 50-yard bulls. (freehand) It is a nice bow that shoots great. I would recommend.

This bow is phenomenal. Its accuracy is unapparelled. I put 200 shots through the Viper today. I don't know what you did to the strings and cables but they never show any wear. I haven't put anything on the strings or even used any rail lube. This is the perfect crossbow.
Todd Bromley
This crossbow fits everything a crossbow hunter would want. The accuracy is unbelievable, with a superb trigger. The new cocking device makes loading and shooting a breeze. Can't think a a single change to make it any better.
