I have NiB BCG that I am having a heck of time trouble shooting.
If I load a single round in the magazine, it functions fine. The empty case is ejected and the bolt is held open. The empty cases are ejected consistently in the same area about 5 to 6 feet to my right and behind me a foot or 2.
If I load more than one round in the magazine, the empty case does not eject and the next round is gets jammed up under the empty case. I have tried a number of different magazines (Pmag, Lancer, Troy, ASC) and the same problem happens.
So, I tried the BCG in a rifle which normally functions fine and the same problem occurs. I took a different BCG and put it in the original rifle, and it works fine. So I am convinced the BCG is the problem. FYI, I lubed the BCG using the method described by Lord Chad.
If I load a magazine and cycle it by hand, the rounds eject fine and it strips the next round into the chamber fine. I tested the BCG by standing it up on the bolt face and it passed the gas ring test. I used the reverse torque test on the gas key screws and it failed, so I changed the gas key screws and torqued them to around 55 ft-pounds. Same problem....So I am at a loss as to what to do next. Any help/advice is much appreciated.
