Armory Dynamics 6-position Carbine receiver extension (buffer tube) is
machined from 7075T6 and manufactured to Mil-Spec specifications.
does Armory Dynamics use 7075T6 over the less expensive 6061 aluminum?
We believe that quality and longevity of the product is our first
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.
