extra piece?

[headcase]

I just got my E-mag back from AGD. While it was there they "upgraded" my superbolt, so I took it out to look at it. Well I reassemble everything and I notice what looks like a thin rubber washer on my table. I figure I had to come out of the marker, but from where. I've never noticed it before. The only place it looks like it fits is between the bolt and the rest of the valve assembly. Anyone know for sure?

It could be the bumper. How big is it? There should be a piece of rubber behind the bolt.

I'm pretty sure that is what it is, it is just a little narrower than the rear of the bolt. I just don't remember there being a bumper before.

That is your bumper. Because it is not quite as wide as the bottem of the bolt you might not notice it at first. It is very important that you keep it on your valve. It stops the bolt from slamming into the valve body with every shot.

Now why didn't I THINK to look at the exploded view? Thanks for verifying my thoughts.
