Disappointed - Wheeler Engineering Delta Series Professional Armorer's Wrench

I bought this wrench based on a few positive reviews I had read on other websites and due to the ergonomic design. However, it is too wide in order to fit between muzzle and barrel for removal/installation of the muzzle break I was hoping to replace. I suppose I can modify the wrench but I would have preferred it worked right out of the package being it wasn’t necessarily a cheap tool..
