buy a Ravin Crossbow. they are so far ahead of the curve it isnt funny. the bolt only touches the bow at the string when you pull the trigger. it doesnt ride down a rail like the old days.
super super accurate. if you buy their bolt$, it is already factory sighted from 20 yards to 100.
i shoot a bow, and i am so used to watching the arrow in flight. wiith a Ravin, it just appears stuck into a target. no rainbow flight. it is insane. i'm waiting for my 80 year old neighbor to realize it is a really bad idea, and sell me his
