    It works very well after an initial period of cleaning and removing one of the dual ejector rods. The bcg had a lot of leftover metal powder clumps and oil from the machining process. I had to remove one of the ejector rods and springs due to the sheer amount of extra effort needed to compress it. The bolt would never fully lock into the barrel extension to chamber the round until I removed one. The dual ejector was way overkill anyway.
