Bump Key Dampeners - Improve your Key Bumping Skill

Easy bumping.

These dampeners are a great idea, they make it so easy! Perfect product. Thanks.

These work great!

I’ve used the standard castration rings and always had pretty good luck with them. These are on a different level though. They aren’t as fragile as rings and they aren’t as easily lost or fumbled. The spacers also give just the right clearance for quick action. I highly recommend.

It works!

They do what they say they will do.
