Don is solid as a rock. And he has the weight room to prove it, lol. Seriously, I've known him for a long time, he has built and repaired serval guns for me, and everything has always gone perfectly including incidences when something wasn't quite right. It happens to everyone. Came back, discussed whatever it was. changed/fixed, back in business. Don't know what more I would want. You'll be fine buying anything he's willing to build.
