Something many might not be paying attention to regarding extractors

[LRRPF52]

First thing I did after reading an earlier post by LRRPF52 on this was to remove those o-rings from my grendel bolts.

Of course I didn't read that until a week after I had ordered BCM extractor upgrade kits with springs and .. o-rings.

I should double check all my AR bolts and do this. I am half tempted to order an extractor removal tool to ease removal and installation of the roll pins.

Did you mean ejector removal tool?

Extractors come out with the firing pin or a punch pushing the extractor pin out with ease, unless you have the O ring. Then it will really be stiff and difficult to remove due to the insane amount of extractor tension created by that combination.
