Anderson LR-10 bolt, I noted the extractor to have little to no movement, upon disassembly I found 2 Orings on the spring. I have heard of one but not 2 O rings. Any experience?

Not broken that I can see, it's my first AR in 308. I just thought there should be a little noticeable movement. So I disassembled the bolt to find the two O rings just gave not heard of 2 O rings before this

Try a test fire with just one and check your ejection of shells and placement of spent rounds on the ground.  You can always replace the second ring if you have any issues.  Maybe it is a 308 caliber concern?

is there a plug in the middle of the spring?

If it functions reliabily, leave it be.
Its not an accident they are there.

Aero 308 bolts also have the 2 o rings! I removed one because it was chewing up the cartridge rim really bad! Working good now no more damage to the rim.

Fired weapon today and as was stated above, the rim of brass was chewed up. Remove one of the O rings and shot again with no damage to the rim. All brass had pretty bad flat spot on the case mouth.
