Why don't you use 7075 in place of 6061?  A big difference in strength.  I haven't seen a finite element analysis on forged 7075 receivers vs. 6061 billets, but I would venture a guess they are stronger than billet 6061s.  I would be a player for your billets if they were 7075.

There is so much information available on the differences between 6061 and 7075 on here that the topic comes up once or twice a month.
Here is the most recent discussion about the topic:
6061 v 7075

We chose 6061-T6 since it works well and fulfills the needs of our lower, if you are set on 7075 unfortunately our lower will not work for you.

Thank You

Beside strength comparisons (7075 being stronger and tougher) 6061 is easier to machine and is cheaper.  Not reasons to use 6061 in my opinion for a high powered rifle.  Ford vs. Chevy? Not exactly.  Colt chose 7075 for valid reasons.  And so did the Gov'ment.

I really like the profile and the design of your uppers and lowers.  Just wish you used 7075.   Maybe in the future.  I hope so.
