DIY poormans adj gas block - braze up the barrel end of the gas tube and drill out in small increments at a time until you get your gas flow required.

To put the AR load development post I was going to do into a simple paragraph..
An AR is no different to a bolt gun in regards to load development - OTHER than having to make the gun run on waste gas
1st you need a load. Remove the gas tube and turn the block 90 deg or slide it forward a bit to block it off.
Do your load development, find the load the gun likes via normal methods.
Once you have a load, THEN make the gun run around it
DONT tweak a load so the gun gasses correctly
Reassemble gas system and test - you will 95+% of the time have to work the gas backwards.
You dont need much gas to make an AR cycle - IMO if you are under gassed - look elsewhere in the gun not at the ammo (providing its close to 'normal' loading)
A Wildcat is against the norm - if it is something oddball the powder speeds may need to be looked at but anything remotely normal is generally a walk in the park
