I came across this post at RFC by “_Shorty” showing photos of his Limbsaver Barrel De-resonator. It is a rubber thing that slips onto a rifle barrel that, in theory, dampens the muzzle vibration improving accuracy.

When I looked at the photo I though it must be a joke. I mean look at it … remind you of anything?

It’s not a joke, they sell it. Maybe it is just me, but I could never put something like that on the end of my rifle.
