Crush washers not allowed - Precision Armament Accu-Washer Muzzle Device Alignment System

I love precision armaments AFAB, I wish it came with a lock nut like others at this price do, but the brain trust at precision armament wanted to make washers. . . 1st of all, if they came on a ring in order, it would be a start, but its just a baggie full of 20 some washer with tiny marks on them. I'm old with bad eyes, I had to hire a grandkid for 20 bucks to put these things in order for me. 2nd of all, why couldn't they make em a color that matches barrels or the afab? no we will just throw this grey we have laying around on it, perfect. Had to recommend em because they do work, you will not get the right one the first time, no matter how many times you read the directions.
