The Armory Dynamics A1 Receiver Extension Buffer Tube
Why does Armory Dynamics use 7075T6 over the less expensive 6061 aluminum? We believe that quality and longevity of the product is our first concern.
7075 aluminum is one of the highest strength aluminum alloys available. Its strength-to weight ratio is excellent and it is ideally used for highly stressed parts. Yes, there are less expensive products made with lower quality 6061 aluminum but when it comes to manufacturing a high quality product we believe you should demand nothing less than top quality.
