I received a new BCG from BCL that was packaged in a shipping carton that was too small for the BCG, alas the BCG was jammed in. When I unpacked the BCG I was concerned that the extractor may be bent as the extractor was taking the force of the small carton (and banging around during shipping). I put a spent shell casing in the bolt/extractor and found it to be very tight, would not easily release the shell.
I proceeded to my firing range to test the new BCG, and on the first shot the BCG jammed it could not eject the shell.
I contacted BCL explained the situation and asked for a new extractor. They have not replied.
I have purchased a DPMS enhanced extractor (from SFRC) and will give that a try.
I am not going to send the BCG back to BCL, as it will cost another $15 for postage.
They don't have the sharpest knife in the drawer doing their shipping.
