Having issues clocking brake. Bought a Troy claymore brake and if I screw it all the way on and clock correctly I can still spin crush washer. It’s like the barrel is threaded too long. If I use 2 crush washers it’s perfect. Is there any issue in doing this or should I order a 5/8x24 jam nut?

I'm no expert, but I would think if the brake doesn't come loose then it's ok to do.

Might check into the various shim kits in lieu of crush washers (or add a shim to the crush washer). Some are single thickness shims that you stack, and others are packs of different size shims where you select the one that clocks your brake properly when tight. I'd also try that brake on another barrel and if you get the same result's chances are it's the brake.

I had the same problem I used blue locktite and it worked out perfectly

I had a similar issue. I went to the range on Saturday and the muzzle brake came loose. When I tightened it back up, it wasn't clocked correctly. I went by my local gunsmith and he put on a new shim, crush washer and used red Loctite. It's set on there now!

Page 13 of the PDF. If yours measures to spec, then your Troy Claymore is the problem.

Both the AR15 and AR10 use the same length spec of .620"
