AR-15 Upper Receiver New GI Spec
this is an update to the CDNN uppers. i took a chance and ordered a couple and this is what they sent me.
the uppers are a3 flat tops with standard feed ramps. the are marked DSA on the front of the upper just above the gas port tube outlet. they have a square forge mark indicating they were forged by BAC. nothing wrong here, i have seen colts use the same upper. i built the middie on one of these from JSE last year.
they are t marked but not outlined. i did trial fit a bolt carrier and charging-handle, they fit fine.
they do have a slight surface imperfection in the finish on the port side just above the rear take down pin. there are some tiny pin-prick like marks in the finish. they are very small and your going to have to look very close to see them. sort of like the finish had a few super tiny bubbles in it that dried and chipped the finish and left these pin-prick like marks.
they could be cosmetic blems or it could be some kind of handling marks--they are so small who cares?
i am happy with them and they will make fine shooters.
