This adjusts with a simple turn of the plug. With either an allen wrench or adjustable/box wrench. When the number is at the 12:00 position that is the port size it is on
Different setups require different amounts of gas depending on the actual gun itself, spring rate, suppressor generated back pressure and ammunition. This plug allows you the ability to “tune” your setup with the last amount of gas necessary to function, reducing gas feedback to the shooter. Your best method for tuning is to start on the largest port working backwards until the gun does not function then go up one click. You may need to adjust to more gas as the gun gets dirtier through the cycle.There is no one setting I can suggest for your setup with all the variables, it will require some testing by the end user.
The plug insert is a consumable part and will erode over time as it is subjected to the hot chamber gasses which act as a type of plasma cutter. It will try to match the size of the port to the plug and erode the steel. this slows and still works as a funnel until eventually working all the way through. Erosion depends heavily on ammunition choice and suppression back pressure. There is not an alloy that I can machine that will prevent this
Please see tutorial HERE
Benefits are that you can “tune” your platform to your ammo for more reliable function and/or less gas feedback while shooting if you have an opened up port especially suppressed with “hotter” ammo
Adjustable plug works with most tri lug suppressors tried on the 4″ tri lug barrel, does not work with my large diameter flash cone on the 4″ tri lug barrel, does work with small diameter flash cone
There are flats on the outer sleeve and a 1/4″ allen cap nut. You must hold the sleeve with a small adjustable wrench while tightening the 1/4″ cap nut. If you only tighten the cap nut without holding the sleeve the nut will come loose. It works as any other jam nut system

This will only work if you have had your port opened up on your gen 2 or ANY Gen 1 as they have larger ports from the factory
All Gen II barrels are now shipping by default with ,055 gas port sizes which means you would have to have it opened up to .0625 in order to properly use this plug. If you are ordering a new barrel from me you can ask for it to have a .0625 port at no extra charge.-12/09/2018
