Armalite AR-30A1 Magazine Interest???

[True Patriot Firearms]

Have located a machine shop that makes custom magazines and is willing to pursue the production of Armalite AR-30a1 5 round magazines that fit both .338LM/.300WM. I am trying to impress upon him the desire of increasing the capacity to 10 rounders, but need to get a feel for general interest in the idea. About 1 year turnaround from date of this post.
