John Galt Speaking.
I shot a 3 gun match on Sunday (Heavy Metal) and after the match, a few of us hung around and shot distant steel for a few minutes.
During that after-match practice, my 308AR started having problems: would eject but not strip off the next round or lock back on an empty mag. Definitely a gas issue. When I got home, I pulled off my handguard and found this:
Definitely bleeding gas. If you look closely, it looks like the pin is either burnt up or corroded away.
Is it a safe bet that my gas block is probably fine and I just need to replace the pin? Background: When I first got it, the gun was originally over-gassed, so I put in a Heavybuffer (heavybuffer.com), which fixed the issue.
Also, when I measured the base where the gas block slides on, it measures .735, not .750; is that area usually tapered? If the consensus is that the gas block might be toast, I may replace with an adjustable gas block and swap out the heavybuffer.
