T6 is not an alloy, it's a heat treatment condition of aluminum
And when you can get a good, reliable, upgradeable, WORKING
King Arms M4 for MUCH less than the $600 or so it's going to cost you to build an M4 from scratch, it's WAY cheaper to just buy a complete gun.
And you will have no headaches due to fitment issues or bran incompatibility.
