AR15 Harmonic Dampeners

[Doubletaptap]

I was told by a fellow shooter to put a "donut" harmonic dampener on my Bushy because it has a 24" free floating barrel.He said it goes on the barrel and stops the barrel vibration when you shoot making it more accurate.

Has anybody used one of these? Does it work?

Where would I get one?

Thanks,
George

I don't know one by that name, but check Precision Shooting articles by Bill Calfee. He's written a lot with dampers on .22 bench rest rifles, but the larger bore bench rest rules have changed and they are going to be showing up on other BR guns now, too. He describes bolt-on dampers with rubber linings so they damp oscillation better. Calfee is a fun read.
