Does anyone know the size of the O-rings on the Knocker Valve on the WE magazines? I need to replace one, but I can't seem to find the size at any local stores or retailers. Specifically, I need the o-ring that is the middle one of the 3, or the middle sized one. I've attached an image. The red line is where the said ring would normally be.
