You can use an "O" ring in place of the lock washer.

I can't tell from the diagram, but is the washer a "wave" washer? If so, those are available, as I use them frequently. Just a thought.

Yes, it is a "wave washer", which will prevent the nuts from rotating once tightened, without digging into anything. They will loosen a bit when everything is heated up a little by firing; I just take up the slack by snugging again if they seem loose. They will come off harder than they went on unless you do it while the gun is still happy (warm, said the Beatles). Use non-marring tools if they are too tough to spin off by hand. Hugh is correct, in that an "O" ring will do, in a pinch.

Sarco is out of the specific original parts, but I'd think that a hardware store would have one to fit in one of those little bins. In this case, close is good enough, unless they have metric ones.
