Slightly recommend

Good idea, but there's a problem 17/02/2017

This system is a good idea. However, there is a serious problem. Most of my barrels (and most I've ever seen) have a small radius on the shoulder where the accu-washer needs to seat. The inner diameter of the accu-washers is too small to account for this. In order to work properly, the accu-washers need to be be beveled on one side of the inner diameter. This kind of defeats the purpose of an easy install, so I can't recommend these.

Recommended with reservations

Needs work 18/11/2015

The way they are marked for thickness hash marks on outside leaves an undesirable appearance. And if your barrel threads have a relief cut at the shoulder it will offset out of center.

If you clean this up it is just as easy to time and index buy moving one shoulder or the other.
