[168] High Speed Vid.: KVP 10oz. buffer has changed. Bolt bounce? https://greyhive.com/videos/watch/ce714d26-adea-4838-b4d8-1b8aee736013 With the cost of tungsten, Kaw Valley Precision has changed their 10oz. buffer to only use 3 internal tungsten weights instead of 4. It's still 10oz., but is it still effective at mitigating bolt bounce with 25% less dead blow mass? I tested using the "worst case scenario" of dropping the bolt on an empty chamber. How do the old and new buffers compare? You be the judge! Many thanks to a viewer for alerting me to this change by KVP!
