Brittle plastic garbage - Wheeler Fine Gunsmith Equipment Delta AR-15 Mag Well Vise Block

Taking my castle nut off and it literally broke with the first bit of pressure. Since OpticsPlanet wants more words of warning for you, I had mounted it to my bench and it shattered at the base. Magazine insert stayed intact, so maybe I can throw it in my vice and give it another shot. Regardless, don’t buy this piece of junk, not sure why OpticsPlanet would be even carry something this worthless.
