I’m looking for a jam nut for my Ruger Precision 338 Lapua but I’ll settle on a crush washer. Seems to be a hard thing to find. The threads on the rifle is 3/4” by 24.

On a side note that was the worst experience ever removing the factory muzzle brake. Like some legendary King Arthur sword from stone type crap. All 225 pounds of me with a cheater bar and a vise. I had to end up boiling the muzzle brake for 7 minutes, and it still was a beast. I was about to pull out the come alongs.
