I received such fast service from Gre'Tan that I felt it proper to post such since lately the topics have been about quality of services. I sent my bolt out to Gre'Tan in Colorado from here in East Tennessee on Tuesday of this week to have the firing pin bushed and fitted. It's Saturday now and I have the bolt back in my rifle. That's four days from here to Colorado and back by priority mail and his work time. It doesn't get any faster. Thanks Greg.
