One of my friend's new GT Flex with the best reflex sight on the planet mounted on it

JMO of course. I'm not speaking for everyone :-)
I re-worked the trigger to get a nice clean 2 lb. pull with NO creep. These are sweet little bows. I just can't see a large heavy and long rifle type scope on this crossbow. He does have an Excal Phoenix with a Simmons 4 power Turkey scope on it. The diamond shaped reticle can be used for 3 distances. We worked out an arrow weight combination to get 20/25/30 yards on it. Pretty neat I think.
