One of the lugs broke on my Model 1 Sales bolt at around 5000 rounds last month. That's pretty good for a bottom-of-the-line part. Coincidentally, I rebuilt the upper with a 16" Noveske barrel and CMT parts a couple of weeks ago. We'll see how long the bolt lasts this time. I bet I get to 10,000 rounds this time (if I can afford it...).
