I don't have any info on the buck buster. But I do have a Parker crossbow it is the Terminator I got it about 3 months a go and I love it I dont have a bad thing to say about it my bother-in-law as the safari Magnum he as hand it fortwo years now and not the frist thing as went worg with it. He killed aboutfive orsix deer with it and I have killed one deer and one coyote withit. But I cant say any thing bad or good about any other crossbows because I have only shoot a Parker.
