I was putting a Timney 510 trigger from one rifle into another earlier this evening and lost the sear spring. I looked for at least an hour, but no dice. I shot Timney Triggers an email at 6:30pm this evening to see if and where I could buy one. I figured I would get a reply tomorrow on a workday, but to my amazement at 8:00pm I get a reply wanting to know my address to send me one. On the bottom of the reply it says "sent from Iphone". Talk about awesome customer service! I would like to thank Timney triggers for going out of your way on a Sunday night to reply.
