if the extractor is missing an O Ring?? Assuming the spring is there, but the ORing isn’t …Just askin.
none of my Auto BCGs have orings, works fine
Of course, as long as nothing else is wrong with the system (rifle/ammo/magazine) and the correct extractor spring is in place. The use of the O ring in addition to the spring is a relatively recent addition to the system (and still considered “optional” by many). It’s just cheap insurance.
Lack of an O ring will not cause an otherwise functioning gun to malfunction.
The O-ring is insurance for carbines and SBR’s that require extra extraction due to the shortened dwell time. You are good without it.
I only use the O-ring in my SBR. No issues without it in my carbines or midlength.
Thanks guys
