lew, i think without buying a whole new gun you can upgrade what you have if you are willing. it'll be cheaper in the long run and maybe you'll get more enjoyment from it. i will not, repeat not sway you from buying a high quality item, but you can improve what you have if you aren't happy. first off, i have a 20" larue, possibly the best gun in the .308 ar universe (slightly embellished….. or not.) it shoots 3/8 moa on the days i do my part. but. now i mean this when i say it. you can make your rifles better. first and maybe the easiest thing you can do is change your triggers. now everyone has a favorite but i recommend geissele. they offer several models to fit your needs. second, if you don't think the performance your getting is good enough, a new match grade barrel by a high quality barrel maker will also give you improvements. fulton, lothar walther, krieger, are all excellent choices. another thing you can do that will help is a free float hand guard. i don't know how reputable your source was but what will wear out or not last???
