I have a DPMS Ar15. That I've never shot. I've been thinking about turning it into a youth gun for my daughter to deer hunt with. My question is for those of you that may have any experience with those types of sights. Are the accurate enough to place a good shot on a deer out to 100 yds? I'm not intrested in debating the merits of a .223 for deer hunting so save it. I will move her up has soon as I feel she is ready. Thanks for any input based on experience
