AR15 BCG missing extractor O-ring

[energizer]

Hi,

I just bought a PSA BCG and while cleaning and lubing it for the first time, I realized that it does not have a O-ring at the extractor ring.

All my other AR15 BCG extractors have an O-ring.

What should I expect from their customer service?

Thanks

Is that the standard now? I have plenty BCGs without O rings.

Yeah they don't all have O-rings. This thread will probably start a huge argument among the local couch operators about the tactical importance of extractor O-rings.

I have had both with and without.....no difference noted.

I must have gotten yours. I got a bolt carrier from PSA that had 2 "O" rings. Needless to say, it didn't work until I removed one.

Well that may be a QC issue then :-)

I haven't opened the second one yet.

No O ring? No problem. Bolt will still function. Majority of the bolts we have in our rifles (military) don’t have that O ring. They have all gone through thousands of rounds w no issues as well.

What gas system length?
Midlength and Rifle length gas system uppers should NOT have an O-ring on the extractor spring.
Midlength and Rifle length should have a blue insert in the extractor spring while carbine should have a black insert.

O-rings are a patch for over-gassed carbine and piston gas systems.
O-rings can even cause failures to eject on lightly gassed uppers.
