The two I received back in November did not.
Nope, none of them do....even though the web site used to say they did.....just checked new site and it has no mention of o-ring when looking through the uppers, but if you go the just the BCG it does say the following:
Milspec Carpenter No. 158® steel bolt
HPT Bolt (High Pressure Tested/ Proof)
MPI Bolt (Magnetic Particle Inspected)
Shot Peened Bolt
Chrome Lined Carrier (AUTO)
Chrome Lined Gas Key
Gas Key Hardened to USGI Specifications
Gas Key Grade 8 Hardened Fasteners
Gas Key Staked Per Mil-Spec
Tool Steel Extractor
Extractor Spring
Black Extractor Insert
Mil-Spec O-Ring
Both of mine had the black insert but no o-ring
PSA should really delete that from the description, so the o-ring Nazi don't have a fit.
Send an IM with your order number and we will send you one.
Some of mine did, others did not. I guess it depends on who assembles the upper?
