That's a good question. I'd like to know that too as I work for an O-ring company. Yup, no kidding. O-rings pay for all my toys. Billion dollar a year business all for little (sometimes very big) o-rings.

#60 0-ring, preferably made of Viton as it's more resistant to solvents.

There is no "#60" on the chart at www.marcorubber.com/sizingchart.htm. That means I can't buy any, since none of the O-ring suppliers I am familiar with use anything except a chart like that. Can anyone identify what a "#60" is in terms of that chart? MK1iii, you're an O-ring pro
 , what do you say?

Go to LOWES.......... they sell 10 pac for $1.29 I think it is, look around the faucet repair stuff. Sears Hardware is another to visit, they come in single pacs, and the dimensions is both packs I think.

4mm ID Viton o-rings. Viton is the only way to go, conventional rubber o-rings will melt. Mine hasn't melted after 200 rapid fire rounds.
Got mine for free when I want to an o-ring warehouse. They only sold to distributors, but gave me a little sack of them. The guys there said the o-rings, Viton or not, are only pennies each. I felt guilty, so I bought them a box of Krispy Cremes. http://www.ar15.com/forums/topic.html?b=3&f=118&t=192741 |

These things are magic. One of my AR10s was failing to eject every round... put in one of these rings and it works like a charm every time.

Oh, by the way, the O-rings I ordered yesterday afternoon, after seeing this thread?
Well, McMaster-Carr chose the "Best Delivery Method" for my order, and they just arrived. Excellent service. Too bad with the 50 I ordered, I don't think I'll need to deal with them again any time soon. Cheers, Otto |
