the B4 market for these is big, I just snapped the FT aluminum ones tuesday while in the lead in the main. These axles are long overdue and I was working on cutting off and drilling the steel axles out and tapping them for 4-40(well dillon was) so no more nut snagging or snapping the extremely weak FT aluminum ones.
Its nice to see Xfactory way ahead of the game on this one.
