So I got in my Wyndham Weaponry Upper today and put it on the lower that I built. I was testing the function, seems to work great. Then I took it apart and the bolt wouldnt come out. I rotated the upper and a piece fell out. Something I have not seen before, did not have this piece at all with the lower build and am unfamiliar with it in an upper. So I was wondering if maybe it was an extra piece from something else that just somehow got lodged in my upper upon shipping? Does it look familiar and does it go on the upper somewhere? It doesnt look "Broken" like it came off of something, I don't see any side of it that looks like it should be attached to metal.
Any help would be great. Thanks in advance!
