Adjustments must be made in a safe area, following all safety rules. “Make sure that the firearms if completely unloaded”
We assume that you have the gas block installed, properly aligned with the barrel gas port, and the gas tube properly installed with the gas block tightened in place.
Once this is done, loosen the front set screw, then turn the adjustment screw on the side in until it stops (do not overtighten). This will restrict gas flow to the gas tube.
Now shoot the rifle in a safe location and direction with 1 round in the magazine. The round should fire, but the bolt should not lock back. This is because there is not enough gas to properly extract and eject the case and lock the bolt back.
Now turn the adjustment screw out 1 full turn. Fire the rifle again with 1 round in the magazine. Continue until the bolt locks open. Once it locks back, you have enough pressure for the rifle to function.
Now back the adjustment screw out another 1/2 turn, then tighten the front set screw. This will lock the adjustment screw in place.
Now test the rifle with 10 rounds, making sure it ejects and functions correctly and locks the bolt back when empty.
You may be done now, or you may need to allow a little more pressure. If you adjust it, do so in ½-turn increments. Remember to loosen the front set screw first and retighten it afterward.

The adjustments must be done in a safe area following all safety rules. “Make sure that the firearms if completely unloaded”
We are assuming that you have the gas block installed, properly aligned with the barrel gas port and the gas tube properly installed with the gas block tightened in place.
Once this is done loosen the front set screw, then turn the adjustment screw on the side in until the screw stops (no not over tighten). This will restrict the gas to going to the gas tube all the way down.
What you want to do now is shoot the rifle at a safe location in a safe direction with 1 round in the magazine.The round should fire and not lock the bolt back. This is because there is not enough gas to properly extract, eject and lock the bolt back.
Now turn the adjustment screw 1 full turn out. Fire the rifle again with 1 round in the magazine. Continue this until the bolt locks open. Once it locks back this is the point where you have enough pressure to function the rifle.
Now back the adjustment screw out 1/2 turn more, then tighten the front set screw. This will lock the adjustment screw in place.
Now test the rifle with 10 rounds making sure it ejects and functions correctly and locks the bolt when empty.
You may be done now or you may need to allow a little more pressure. If you do adjust do so at ½ turn increments. Remember to loosen the front set screw first and re-tighten after.
