Great design, terrible material choice

I purchased this kit for an upper build I was doing as a gift for a friend. The design is fantastic in its versatility but the choice of a low grade and strength aluminum (6061 or 2024) as the manufacturing material was wrong considering the limited length of threaded holes for both clamping to the barrel and attaching the picatinny rail sections. Both the clamping set screws and the screws for attaching rail sections stripped out without any effort and upon examining the screws for the rail sections the screws were only holding on 1-1/2 to 2 complete turns of the thread. Standard manufacturing practice is that when putting a screw into aluminum of any grade you must go twice the diameter of the screw in number of threads to properly hold. As previously stated this is a fantastic design but would be better off if manufactured out of steel or titanium.
