Because of this thread, and others like it, I reached out to Southern Precision yesterday morning. I've been sitting on an MPA Hybrid Chassis for a little while, and have been wanting to get a barreled action done.
Russ responded to my initial email in 30 minutes with a preliminary estimate. I couldn't hardly believe it. He then answered a couple of questions I had, made some suggestions and in less than 12 hours, he sent me the final invoice with the requested payment method.
Top notch customer service, and my build hasn't even started yet. Thanks to everyone for this recommendation.
