Excellent company and customer service. Tuning a trigger and the owner is sending various of them to me to try out and shoot with. Ensuring I get the right combination in. Very helpful and informative people. Thank you
I couldn’t be more impressed with this company’s service. To top it all off, the name of my rifle is American Resistance. Awesome.
