Questions & Answers
How many are in there? Just 1?

It comes with a complete pack. One washer for each thickness level (18 in all). It works off a system where you put the thickest washer on (marks on side indicate thickness). Then, depending on where the muzzle device lands, it tells you what size to put on so it properly indexes once you torque to spec. Very easy. Would highly recommend.

One pack can probably do 2-3 rifles, but it depends.

The best you can use by Lazarus, Verified Owner, May 9, 2026

accuwasher by bob, Verified Owner, July 11, 2026
This is the only system I use to attach any of my muzzle devices. You have to look up your barrel diameter and thread pitch for the same size of accuwasher. Just remember the heavy grooves are 5 and the thin grooves are 1. After each washer, hand-scr...
