[ARCHIVED THREAD] - newbie with a newbie question about bcg

Posted: 11/19/2008 8:50:04 PM EDT

Hey gang,
I am new to the AR system and just received my BCM middie upper. I got a new bolt and it came with an o-ring. Where does the o-ring go? I am assuming it is for the gas tube. I searched for a diagram with no luck.

Thanks

Just start looking for QUIB's post on maintenance/cleaning/disassmbly - you'll start learning a ton in a hurry, highly recommended.
I run the black donut spacer on the bolts I run with crappy ammunition, but with a wolff springs the standard extractor setup is just fine.
