Got my DCM upper a couple of days ago, it is absolutely perfect. The black teflon finish over the stainless bbl looks great, the sights are rock solid, freefloated handguards fit
perfectly. All at a helluva bargain price. I haven't shot it yet but will let you how it works out. If it shoots half as good as it looks I expect 1/4 MOA.
