Does not fit 7/8 contender barrel - Choate Tool Tc 14in Bull Barrel Contender Forend

This forend comes nowhere near fitting a 7/8 barre, as it leaves a large gap between the channel and the barrel. I'm contributing this to very poor manufacturing and quality control. At the muzzle end, the barrel channel measures 0.791", in the middle it measures 0.747", and at the back 0.783". Either way, it won't fit my standard diameter tapered Contender barrel or my bull barrel. Both sit very high with a very noticeable gap.
