Aero Defense/Aero Precision roots are deeply tied to aerospace, and our drive for clean, perfect engineering and machining stems from that. When you’re building something that will fly in the air, there is no margin for error. We take that same approach in the firearms industry. Not every manufacturer will have razor thin tolerance levels. All our products are made in our state of the art manufactuing facility here in the U.S and carry a limited lifetime warrenty.
