Aggie,
Do you have or do you plan on using a suppressor with the subsonics?...My 300BLK has intermittent issues with cycling/locking back if I don't use the suppressor (and is acknowledged as a potential issue by AAC/Noveske). The suppressor will increase back pressure and may solve your issue (if you aren't using one).
