Missing the entire buffer tube - Reptilia RECC E Stock for AR15/M16 Carbine Length

I was super excited for this fde carbine stock/buffer system to finish my build. I waited a few weeks for my package to show up and when it arrived I noticed the package had looked like it was previously opened when I opened it up to my surprise there was no buffer tube or screw deeming the stock useless. I’m sure the stock would of been a great addition to my build but now hopefully the company or optics planet will make it right
