Just for the record, i have only met derrick 3 times, and it has been sam from carra out door sports in bellville that has got me shooting crossbows this yr, i like crossbows but they are just rattle guns, the trouble with them is that they dont like cheap scopes , and thats what chinese scopes are, and tasco falls in the same bunch, unless you spend atleast 500 or so dollars. Ingal uses a leopold and it shows, he great and so is the scope.
I just thought i would try this russian scope, although cheap its self, this model of scope has been around along time, and used in many rough areas of the world then and now, would that not make it some what dependable, i still prefer my leopold, but i would never take a chance on useing it on a rattle gun.

Unless you want to be put on ignore by everyone, stop associating crossbows with guns! It is no where near the truth and anyone who has any respectable knowledge think very poorly of you because of an apparent ignorances of crossbows.
