Thread: CZ 455 .17 HMR American Synthetic

@Seventenths please whatever you do, don't use a Dremel. By far the better way to improve the feel of the action is to apply a thin coat of fine valve grinding paste and work the bolt back and forward repeatedly. This way the smoothing process will work the areas that need attention automatically. Wash the paste out and repeat, until you are happy.

I've done this with several rifles over the years, including CZs, and it works very well. It only removes a tiny bit of material, only in the place where material needs to be removed.

Dremels can accidentally remove more material than required (very easily) and in places where material should stay put!
