I have a Jennings CK3.4R and can't say enough good about it. I bought it from Hunters Friend, and have to say I'm very impressed with it. Seems to shoot very consistent groups and a pretty fast speed. It looks great, isn't too heavy, very little hand shock, is quiet. I just can't findanything wrong with it. I'm prety sure if you're father gets one he will love it, i certainly love mine.
