Great customer service - Volquartsen Firearms THM S&W M&P 15-22 Sport Lightweight Threaded Barrel

I installed the barrel and extractor no problem. But the firing pin was slightly bowed and wouldn't go in all the way. I emailed volquartsen directly at midnight on a Friday and was responded to at 10am Saturday morning. They asked for my address and sent the part asap. I sent 2 emails and one was to respond with my information. Customer service on this level is hard to find these days, and I for one think thats more important than the fact that the product is the best on the market.
