Aero Precisionís roots are deeply tied to aerospace, and our drive for clean, perfect engineering and machining stems from that. When youíre 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. Not every manufacturer will personally oversee the development, design and machining of every part that comes off the line. Weíre not every manufacturer.
