    Suppressed it is for sure overgassed. 1 o'clock ejection is a symptom of that all day. Are you running suppressed?

    I'm not running suppressed. However with that setup I was having overgassed symptoms. Forward ejection patterns. Soon as I changed the buffer/spring, it has run great ever since.

    Also, the BA Hanson barrels use a 0.076" gas port.

    I’ve got a 10.3* MK18 and I installed the VLTOR A5 buffer system and a ported charging handle best move ever. Had to change out to the VLTOR rifle length buffer tube, Green SpringCo spring and a heavy buffer. Originally had a PSA 11 upper that shot gas all over my face when shooting suppressed. Now that I’ve got the MK18 upper and the VLTOR system and ported charging handle I have yet to get any gas in my face. Plus the recoil has softened a little as well.

    jcomr1 already mentioned the Gemtech adjustable gas block. I put one on a 300 BO SBR and it seems to have helped. (I use a brass catcher so I haven't seen where the brass throws) I run this gun suppressed and unsuppressed with subsonic and supersonic. It ran ok before the change, but it sure helped my brass have less dents/damage.
