"Roger, different. The #60 "O" rings commonly available would work for a short time in a pinch (and i have used a whole bunch of them on my guns as well as others).
Having said that, we were able to purchase a great quantity of the Crane type at a significant savings."
take it for what its worth. i know i saw another mention of #60 somewhere else on here. ill look some more.
Honestly the Bravo Company extractor upgrade kit is more than worth it. I honestly think the correct insert along with the correct spring is a lot more important than the O-ring.
As a matter of fact I was having issues running the O-ring in my LMT 14.5". There was too much extractor tension. It was shaving brass from the cartridges and causing the ejector to become stuck. Removed the O-ring, problem solved. I only use the O-ring when running Wolf or Barnaul steel cased ammo.
The ones that I have just gotten are from McMaster-Carr #75 Viton Size 006, 1/8" ID & 1/4" OD. ETA: Part # 9464K11 = $5.22/100.
1201T16 - the mil-spec version. (apparently more solvent-resistant)
McMaster-Carr - if they don't carry something, that's because you don't need it :)
