    Reducing extractor vibration?

    Looking at building my next AR but I want to do the best I can to reduce extractor vibration.

    Do I need a specific type of extractor, spring, or O-ring?
    Why do the loudest do the least?

    I believe KAC has a new bolt with dual ejectors that is specifically designed to mitigate extractor vibration. I can’t speak for anyone else, but extractor vibration has been my biggest issue with the AR-15 platform, and this is a welcome development.

    I think the included Viton O-rings, usually tossed in the trash, with new bolts can help reduce the rigorous extractor vibrations.

    This. If I had a dollar for every vibrating-extractor based malfunction I've had, I'd actually shoot my AR.

    Extractor vibration? First time I've heard of this. What exactly is that, if you don't mind me asking?

    30 years on the AR, and I've never heard of this tragic situation.

    Also, KAC's bolt isn't new, but it does indeed have dual extractor springs.

    The extractor does not vibrate.

    It does bounce occasionally. Understanding Extractor Lift in the M16 Family of Weapons

    They just announced the E3.2 bolt is shipping yesterday.

    I donít keep up with social media so Iím a bit behind the times. But they did say it reduces extractor vibration so I think I will go with an SR15 upper.

    E3.2 Bolt. Finally a solution to the vibrating extractor problem that’s been plaguing just all these years.

    The revised it?

    We shoot Pappabears "Jack Leuba" SR15 almost every week. Awesome gun. But for parts commonality, I'd really lean towards the standard bolt. Not that bolt breakage is a big issue with either design, but my conservative side likes to stay on the beaten path most of the time.
