I grew up with the benefit of my father's tutelage concerning precision shooting. Started loading my own ammo @ 16. I'm now pushing 60. In all that time I've owned many bolt, lever, & single shot rifles--all with the intent to shoot bug hole groups. Never interested in an AR/semi-auto centerfire---until recently. I try to befriend almost any @ my local range & come to the conclusion that these young AR shooters just want to have fun & truly enjoy our shooting sport. By far, most are respectful, rule abiding members. (There's always the one that thinks it's MY responsibility to keep their brass from hitting me). Perhaps, as one wise poster mentioned earlier, they simply follow what they see on the internet or what their friends do(blind leading the blind). So, to keep things interesting I built my own version of a precision AR 223. I must say--It's FUN! No blasting or plinking--all with a precision goal in mind. This has renewed my interest in shooting again. A new(to me) facet of the activity I fell in love with more than 40 yrs ago.
