is there a fieldstrip screw oring in the RT parts kit?

or do you know of any other way to make a quick sub for the fieldstrip screw oring? only one of them broke, I don't understand how, but I'm sure it was something I did.
Thanks for the help!

The RT parts kit contains o-rings that will replace the banjo bolt o-rings on the original Automag RT. The urethane washer on the Mag, RT-Pro, E-Mag field strip screw is not in a parts kit if that's what you're thinking about.
