Take a look at their videos on the RobArm web site. It says to put them in one way for dry dusty conditions and the other way for some other reason. It will tell you there!
Good Job!

Actually it's not a split washer, it's called a Peel Washer. This was the first time I have ever come across such a thing. You heat it up and delaminate a small thin slice at a time until you wind up with just exactly the thickness washer you need for the brake/FH to line up properly as Aussie said with the logo aligned straight up.You use the split washers to find the position where the muzzle break is indexed to the top (The symbol I think is on the top) and it should work as advertised.
