Redoing my AR and am contemplating building a whole new upper or buying a built one. Primarily all be used for coyote hunting and the occasional shoot. Had a .223 Wylde upper for the apparent "flexibility" and was not to well versed in .223 vs 5.56 at the time. Debating the same chambering or possibly going to a .224 Valkyrie but am very apprehensive of that chambering. If I built the upper, looking at a Rosco 18" or similar Faxon but am open to others (had a green mountain barrel on my previous upper). Am not opposed to buying a PSA because of the price point but, and this is a big but, my concern is I am going to spend the same as a "premium" upper as I would buying a cheaper upper and swapping out for better parts. Thanks!
