I recently had occam gas block installed by AK John.

The gun would not cycle subs on the highest gas setting, I figured it was because of the Chinese ported gas tube.

I ordered a WPB gas tube, it will still not cycle the subsonic ammo.

what should be my next step?
drill out the largest hole on the gas plug and go from there?

I would love to get this thing running correctly, the whole reason for the adjustable gas block was so I could adjust the gas to cycle subs or supers on the fly.

Thanks
