Kinda can guess what chugging is.
What causes it, and what's fixing to go wrong?

Gas system isuue mostly.
Carbon, bullet jacket shavings , heat, loose gas plugs
Slow down rate of fire.
Wpn fixing to puke on ya unless you can pull the piston.
Clean it up
Punch out gas tube with the brush.
And get that piston moving freely to hear it click back and forth in the tube tilting it back and forth with the bolt assembly locked back.

Worst thing to do is oil a 60 gas system heavy.
Very very light finger print of oil at the most.
They gave us graphite during desert storm.
Mostly for the bolt and feed tray and feed pawl system
Worthless.....

Light clp up top .
Dryish in the gas...
