ditto on the WhiteOak recommendation. John built ours on new Rock River lower & upper...... we got the 1/4 click rear sight mentioned above. we chose the Kreiger 1-7 stainless........with a float tube....... he is known as the best AR smith in the USA.....as far as I know, his only equals are the military team armorers........... As far as off the rack........ Les Baer builds very dammed nice rifles..... that are probably more accurate than most guys can shoot......... Armalite does too, our late Major Culver & Master Guns Gus Fisher both endorsed their rifles..........& their judgement carries a lot of weight here....... I don't know if the average guy could come to any where near their equal in quality.
be safe, enjoy life, journey well
