Odin adjustable gas block ?

[Bigs28]

My gas block has a click every 1/3rd rotation. I started with it closed, opened about 2 full turns, loaded one round and fired. Bolt did not lock open. From there i repeated the process 1 click at a time till the bolt locked open. I then opened it one more click and left it alone. I've shot sst, amax, and eld m with no problems.
