Hi Lee,
Saw your reply, since my post I had done work on my FAL's.
FAL #1: DSA 16" heavy barrel, opened to .116--- hot and dirty
it runs on 4.5 setting.
FAL #2: DSA stg-58 16" standard, opened to .118 (3mm)
it runs like an AK, hot and dirty runs on setting 6
all is good---Why did I do this--- before FAL #1 hot and
dirty, I had to put setting on #1 to make it cycle.
I'm very happy the way they work now.
