As a listener of We Like Shooting i have heard over and over about how incredible the DOC MD-15 is. I am a husband, a father, and whatever else those titles demand, and my money... My money is hard won.
This is way more than a simple decision. This is a lifeline. This is a tool that is absolutely essential and/or critical to one's ability to survive the most desperate of situations.
I have always had a "healthy" sense of mistrust or doubt, but when I listened to Nathan Mitchell on the podcast, I heard a guy that spoke modestly about building a rifle that he could trust in the moments that count. The things he said just made sense, choosing redundancy and robustness over the fiscally minded industry standards. I recieved my 16' DOC a few days ago, and I am absolutely floored by the build quality. The fit and finish are just as impressive. Thank you Mitchell Defense for delivering this beautiful, heirloom quality rifle that a man with a family can afford.

Good Company, shipped fast, and Customer Service actually ANSWERS THE PHONE! I had a question before I ordered, spoke to some guy named Nathan. He helped me out, but could use more training. This is a good American Company that makes Great rifles.

Good people. Had some questions because I'm new to this kind of gun, and they took the time to explain things and make recommendations for accessories. If what you want isn't in stock, just keep checking, it'll probably be back in a day or 2. I saw my gun go in and out of stock a dozen times before I was finally ready to pull the trigger. Then it was out of stock. But it came back in the next day.

For a serious do anything go to rifle, choose Mitchell Defense. Shipping was fast and reasonable, the website is easy to navigate and customer service lets one speak with a real person instead of an automated recording.
