BE DYNAMIC

We design high quality AR-15 uppers using parts from companies that you already know, love, and trust in the ever-evolving gun industry. We add our own personal touch by using our CNC mill to skeletonize uppers and bolt carrier groups and offering custom laser engraving on our products. If you have your own ideas for customization, just email us and we will try to make it happen. All of our uppers are tested before they ship to ensure you are receiving a quality product.
