Broke on literally the first turn. - AIM Sports Inc AR Armorers Kit

I was stoked to get this kit, and waited almost a month to finally receive it in the mail from Optics Planet. This kit was the only thing stopping me from completing my extreme makeover on my Smith & Wesson M&P Sport 2. I was unhappy with how wobbly my lower receiver was when I mounted it on the vice block, only to go to loosen the castle nut and have the armorer's wrench break on literally my first crank. For the record, the castle nut did not loosen, remained completely torqued, and the tooth on the wrench came completely off. My overall experience from shipping time to quality of the product is less than one star, however that wasn't an option.
