Jason and Lee are the best. They helped my Son-in-law build his AR and stood behind the product with solid customer service. I was looking for a new trap gun for my daughter, they found a new Browning BT99 Micro and got a great price. I run a firearms training company and I recommend them to my students.

This is a great group of guys with the knowledge needed to build an AR at almost any budget. They're willing to work to get you the parts you need, and will walk you through the process to get your build done exactly how you want.

Great guys to work with. They helped me with getting the parts I needed for my first AR build and also walked me through the build and checking that everything was installed properly.

Talked with these guys prior to going in to do the actual build, so they were able to source some hard to find specialty parts for my build. Build went great and they came out with me to shoot it after to ensure the less common specialty parts were functioning correctly. Can’t wait to build another one with them.
