O ring ??

[Rollin Thunder]

Newbie here,
I'm new to the AR however, I've been around firearms my entire life. I just got my first AR and started cleaning it, no problems there. I break it down to your basic field strip, clean everything and put back together.

So far all is good.... I look on my bench and there is a rubber O ring laying on the bench. I've looked in the manual, I looked at a schematic, I can't find a rubber
O ring.

Am I missing something here? I could swear that my bench was clean and clear when I started.

Is there an O ring in these puppies?

Thanx

How big is it?

Is it like small that might fit around the extractor plunger and spring? Some ARs come with that upgrade and some do not.

oops. indeed- probably extractor o-ring. sort of odd that it would just fall off, though. what kind of gun?

[Rollin Thunder]

No, it can't the extractor o ring, I didn't break that down.
The O ring is about the size of a pinky finger. Almost like it would fit in the breech??
Heck, it may have been on the bench all along.

Thanx

no o-ring goes in the chamber.. maybe it is a chunk of packaging or something.. or left over from when you rebuilt your lawn sprinkler there and just set the gun right on it.

a picture would speak a thousand words

It could have been on the rear of the upper. (over the nub that the rear take down pin goes thru.

I think some apes have tried to put them there to get tighter lower/upper fit. Just leave it out.

regardless of if its from that rifle or not, its not needed.

[Rollin Thunder]

It's not needed, ah! that's what I needed to hear.

As far as sprinklers go, It's funny you said that, I had some up there about a week ago.

You can probably sell that part on Gunbroker right now as I hear that they are pretty rare.:eek:
