Simple as can be. I was able to tighten a castle nut without it breaking.

Made of a thick cut of steel, nice clean finish, fits the castle nut on my AR like it should.

If you're just putting together the occasional lower, it works fine for the castle nut, it's a solid alternative to spending 3x as much on an armorers wrench you may use only once or twice after the occasional boating accident.

Does what it's meant to do. Not as clean of a fit as I'd like for it to be, but it works.
