Returned Horton, Bought Ten Point
I have been vertical bow hunting a long time and was ready to try crossbow hunting (so I could ground hunt better without lugging stands in and out of the woods).
I did some research and decided to get a Horton 175 Realtree with red dot scope. I know, it isn't get best on the market, but it was available locally and was in my budget. Brought the bow home to site it, but I couldn't for the life of me get the red dot sited at 20 yards. I tried and tried. I thought I was jerking or something. After about 20 shots I decided to forget adjusting the sight and just shoot 9-12 rounds.
What I found was that it would shoot dead on for 2-4 shots, then the scope would knock itself off 3-6 inches up or down, and 3-6 inches left or right. It would then shot very tight groups in that spot for 2-4 shots, and the same thing would happen again.
I returned the x-bow and started making some calls. I ended up on the phone with a local shop (Louisiana Outdoors in Pearl River, La), and got some excellent advice. I decided to go see the guy. The first thing he told me was that he no longer orders x-bows with red dot scopes because of how many complaints he got.
In the end, I blew my budget and bought a Ten Point Titan HLX with the 3x multi dot scope, and I COULDN'T BE HAPPIER. It took 3 shots to zero the scope and the x-bow shoots wonderfully.
I only post this for others to consider before making a x-bow purchase. I am not saying there aren't good red dot packages out there.
