Loose Gas Key - Unintended consequences
So I got my BCG back from Bravo Co. A note about their customer service: they replaced the key and re-staked it. They also replaced the cam pin that was quite worn, but still looked like it had some life in it, and appear to have test fired it to ensure it was operating properly. Can't say enough about their CS!
So here's a new wrinkle...I took my 11.5" rifle out to test out the BCG and it runs ok, but I noticed that the rifle is now ejecting the cases rather aggressively forward...like 1 o'clockish. No cycling issues, but I am little concerned now, not to mention that at the indoor range 90% of my brass was lost to the brass god ahead of the firing line. Before the gas key had come loose, it was ejecting over my shoulder, about 4 o'clock. I have been running an H buffer, and the rifle had seen well over 2500 rds fired without an issue.
I've already ordered an H3 buffer and I currently have an H2 I can use to slow down the cycle rate. Question is...does it matter where it is ejecting (other than the annoying loss of brass) as long as it cycles ok? Of pure curiosity, is it possible there was a bit of a gas leak in the key for quite a while and that allowed it to cycle slower using an H buffer? I went to a class in early Sep and ran 1000ish rds thru it, which may have accelerated the gas key issue that appeared shortly afterward.

BCM says they replaced the key, properly torqued the bolts and staked the key. Thanks to all and special thanks ro 26inf who offered to restake a new gas key.
