HD extractor springs & CRANE O-rings

[Iraqgunz]

You don't need the O-ring. People need to look at why this issue came about, those who were shooting and what they are shooting. Not one of my AR's needs an O-ring to extract and function properly.

Ok...I've read this whole thread several times over the last few years and I'm starting to have a question.

I use CS 4 coil springs from Tactical Springs w/ black insert and Viton Crane O-Rings in my 14.5" middy. I am now retaining my brass and reloading it.

Would one do better to stay with this set up or upgrade to a CS 5 coil w/ black insert and no O-Ring to minimize rim damage (assuming no FTF/FTE)?

Thoughts?

Colt 6920, about 1,000 rounds through it, on a recent cleaning noticed no O ring, just the "gold" spring with black insert. Do I need the O ring? Seems to run fine, no extraction issues. I've read through this thread and am confused as to whether or not I need this ring or not. What extraction problems could arise with or without O ring? Did it ship without the O ring, or did I loose it?

Thanks

You have not needed the O-ring since late 2007 when Colt got the copper spring through military testing. Some springs need O-rings, but HD springs do not and the copper spring is the standard issue HD spring.
