This past summer I bought a brand new Horton 175 team real-tree crossbow with complete package, which is multi-reticule red-dot scope, three bolts, quiver and silencers for 350 instead of 500.  The crossbow is great, however, I am having issues with my scope.  
I have re-sighted it in four different times.  After each time I completed the sighted in, I was hitting bulls-eye at 20 and 30 yards.  When I would come to shoot again, it would be off by at least three inches or more.  Know, the scope rings and mount are tight.  When I sighting in the scope, I was following the directions.  
Personally, I am not happy with this this scope.  Some of my friends rec commend that I obtain a regular crossbow scope.  I looked at Dick's website and found a tru-glo for 100 dollars that is multi-reticule scope; I can also buy Horton mount with rings for another 50. 
What Should I do?  Should I call up Horton and see what they say?  Should I invest into this good scope for the long run?  Can I solve this a different way?  Know, this is the first crossbow I have ever own, so if you have any other pointers say them.  I want to solve this cheap, however I want to solve it for good so it can last me 10, 15 and possibly 20 years.  What do you think?
