Just ordered a new BCM Bolt Carrier Group. It came with a little rubber washer. What the hell is the washer for? Thx

Extractor o-ring?

What size is it/where did it come from?

Sounds like it came with an extra extractor O-ring. Remove the extractor and see if there is already an O-ring installed.

IIRC, Bravo Co doesn't pre-install the O-ring, as a lot of folks don't feel the need for it.

I think they are overkill.

My BCM upper and BCG didn't come with one at all.

It's really small.....you could just fit the tip of a pencil through it. It was part of the sealed packaging of the bolt.....

Not necessary but if you decide to use it do it like this.

Hell yeah pal, thanks i would of missed and you are exactly right. Until you posted that "o" in the package looked like a typical o insert on a package to hang on a display.

Its not needed. Its for if you have some serious extraction issues.
