How to adjust gas setting

What is the proper initial setting for the gas on a FAL when unsure of the ammo to be used?

Once operational, how do you properly dial-in the setting for reliability, etc?

Close it off and open a couple of clicks at a time till you get a stovepipe. Then close it a couple of clicks for the final setting. Brass should should eject about 6-10 ft

Close the gas regulator completely

Insert magazine with one round

Chamber round and fire.

If round is ejected and bolt locks o the rear, open the gas regulator 2 clicks and repeat the process.

Continue until a casing gets stuck in the chamber.

When case gets stuck, remove the mag, hold rifle vertically with the muzzle up. lift the rifle up with right hand until it is about a foot above a sturdy and hard surface. Place the heel of left hand on charging hand and bring the rifle down sharply onto hard surface. Casing should be ejected. If not, repeat the process until it is ejected.

Once casing is ejected, close gas regulator 2 clicks.

Insert mag with one round. Fire to confirm that the case is ejected and bolt locks to the rear. Once this happens, gas is set for that ammo.

thought it was the opposite- open gas all the way, load round, fire.
round fails to eject.
close gas a click, load another round and fire. repeat until round ejects.
then close gas two more clicks.
?

In a perfect world, proper gas setting will be about 5 (middle setting), ejecting casing 6-10 '.

If you want to pound your rifle into the deck repeatedly, then start with the gas open. If you just want to do the pogo once, then start with the gas closed.

If the gas regulator is closed, you are getting maximum gas...

If the gas regulator is completely open, you are getting minimum gas...

Keep in mind that the gas regulator regulates exhausted gas, the more you exhaust (opening the hole), the less you have acting on the gas piston and the less you are beating up the action.

This is the correct method.

Keep closing gas until round ejects and bolt locks to the rear....then one more click on the gas......Should end up at around 4 on the regulator....unless you are using ZQI or Cavim...then 1.....its weak. Port, South African German,....4.

Funny, my Enterprise Arms was down to 2 using Hirtenberger. I think the gas port in the barrel is too small. I may have to drill it out to get more gas.

Whilst I have heard of cases sticking and the pongo I have never seen this happen in original FAL rifles. Even using the grenade setting the case pulls out without any extra effort on the charging handle. The FAL seems remarkably tolerant in this respect. I suppose it could happen with hotter ammo and or non chrome lined chambers.

Not on any of mine. They get stuck and that's why I'm fully closed then open as I'm searching for the setting cause I don't like slamming the butt down to snatch the ch
