Saw these guys on social media and had to give them a shot. This thing is well build, and the custom cerekote is perfect. No better way to celebrate America 250. I can definitely tell this is a high quality product, and will back for more. Excited to see what they introduce next!!!!

Really happy with this rifle and the FRS setup. The finish looks even better in person and it shoots great. Everything felt solid and worked like it should. Definetly gets alot of attention at the range. Have several friends that are planning to get one.
