    They can be rough on rims when combined with the newer, heavier coil springs.

    No, I have not noticed any marks, damage, etc to any brass fired through my rifle the the o-ring upgrade.

    That set up is a little more rough on brass but well worth it for a properly functioning gun. Mostly rougher on the rims.

    Only needed if the extractor slips over the rim. Wolff and Tactical Springs make stronger springs. Many add these even though they had no problems and created some they didn't have. If the extractor spring/ring is too strong it will overide the ejector and cause stovepipes.

    Thanks for the feedback. One report of no impact and two reports of it being rough on case rims. Plus, one report that it may actually create a problem where none exists.

    For those who have seen the O-ring be rough on rims, did it affect the life of your brass?

    I have one of these O-rings and am trying to decide whether to actually use it. I've never seen a failure to extract without one, but that doesn't mean anything. I also never want to see an FTE. That's not realistic though unless I retire the gun.
