I have a Chinese Vortex crossfire II on my crossbow and it works good. I bought a Hawke crossbow scope for it first and sent it back because it was junk {fast focus eye piece way too loose and wobbly}. It's tough to find a crossbow scope that isn't made in China. I also have a couple of cheap Chinese Simmons scopes on .22 LR plinkers and they too work well. All of my hunting rifles have scopes made in USA {Leupold}, Japan {Weaver, Bushnell Elite} or the Philippines {Nikon} but I can't justify spending much on a scope for a cheap plinker.
