Well first- stop cleaning and put the can back on. Yes your can is a high back pressure can and it is more of a challange to get that one working correctly with an AR than others, but it can be done. A low back pressure can will help. A Gas Buster charging handle of whatever brand/type will help a bit with gas to face.
BCM’s are gassed pretty heavy. You can do all sorts of things to try to help it, but they are all bandaids. The simplest and probably most reliable way is to get a reduced sized gas tube from Black River Tactical. That’s and an H2 or H3 buffer would be my first steps.
Don’t clean. AR’s do not need to be clean to function perfectly, quite the opposite. Keep them lubed and you are good.

Well over 60,000 rounds, 100% suppressed on the upper, no cleaning at all- 2 malfunctions caused by the firing pin retaining pin shearing off in the upper at about 40k rounds. No clue on the lower, it’s been in constant use since 2010- for reference this upper has only been in use since 2019.

I can show dozens more. AR’s do not need to be clean- they are filthy little hobbitses and they like it.
