Yep, another broken-extractor thread

[SDW]

My apologies I thought you was the same member here not long back that had broke several extractors.

As to your load, I dont really care how hot you run it. It's your rifle and your health do as you choose.

I'm just giving you the best advice I can to fix the issue that caused your extractor to break. Just because you have standard equipment installed doesnt mean the rifle cant be or go overgassed.

Even with all OEM equipment setup rifle length in 556 can be overgassed. As it was designed to be overgassed too keep running under combat situations.

3:30 and later on the clock is undergassed. Anything earlier then 3 is over gassed and getting worse.

Thank you for the info!

I'm sure you're right about it being overgassed by design. Kind of funny though, w/o the 'modern' deflector the brass seems to go any which way. At least it does with my old M16a1 upper. So I don't know if we could use the 'O'clock' method as reliably I don't think, anyway. I never experimented with light an heavy loads in that upper to see what the brass would do consistently. And it's getting off topic.
