PSA Adjustable Gas Block Questions.

[NeilVT79]

Unless there is more than one model of gas block, simply looking at where the set screw on the side of the block is in relation to the gas port shows which is which. Side screw on mine is well forward of the gas port.

PSA themselves have caused confusion on this as well. https://www.ar15.com/forums/AR-15/Adjust...18-732340/

There may be different types, Im using the AGB that came with my PSA 12" upper. The side screw all the way in cuts off my gas completely.
