Awesome! (29/05/2013)

Was not sure about these washers when I saw them online...I was proven wrong! These are awesome! Super easy to install! Easier to use than crush washers! Will purchase these from now on when installing flash hiders, comps, and brakes!

Great Product (12/04/2014)

the guy that invented these deservs a raise. such a simple concept but work wonders when installing a comp. Always get the right torque everytime, and never have to worry about changing accuracy.

Made Me A Believer (14/05/2014)

I didn't quite get it when I ordered them, but the instructions are super simple and intuitive. Two attempts in about 10 minutes, and I got my comp torqued. That's compared to 30 minutes with some spare AAC shims to get kinda close.
I was worried it would look bad or cheap on my stainless barrel and comp, but it's hardly noticeable. Might try to polish it, since the shim is stainless.

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.

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.
