Something you might want to think about,pull the bbl and receiver out of the stock,and look at the arrangement of your short stroke gas system.Think about those lead bullets at the upper end of lead bullet velocity wiping by the gas port.Think about how you would de-lead the gas port.
Then,just for fun,poke around and see if you can find bulk fmj's pretty cheap.
Undoubtedly,someone will reply he has fired 784,000 lead bullets through a carbine with no trouble.Thats OK.
I hesitate shooting lead past a gas port I cannot easily clean.
PS,I work for the same pay!!I prefer to call myself a facilties hygenist!!
