Something to watch for - I have had two barrels that had a rounded shoulder/neck vs. a hard sharp 90. The I.D. of these washers stay pretty close in diameter to the muzzle threads, and the inside edge of the washers were actually sitting on the curve of the shoulder, instead of sitting perfectly flat on them. I could see light between the washer and the shoulder. I quickly solved this by 45'ing the inside edge of one side of the washer ( a very tiny amount did it, like a 64th inch bevel.) Just something to watch for. One barrel was a stainless Noveske, the other was a LW DD barrel. My other bunches of barrels I have had a sharp shoulder.
Real tempted to pick one of these up fer shits. But geez I've got a ton of MDs already. This thing's a heavy bitch at 3oz. But then, my SF MDs are pretty heavy.
