16” 5.56 Slimline Billet Rifle
Hands down the best customer service over ever experienced when it came to getting what I was looking for. I had no issues communicating with them whenever I had a question about something. The rifle? I got way more out of the rifle than what I expected. You can definitely tell they took their time making sure everything was properly assembled and staked properly. Highly recommend.
