Great wrench - Midwest Industries AR Professional Armorer's Wrench

There's a lot of junk wrenches on the market. This is not one of them. I've yet to run into a barrel nut or muzzle device that it doesn't adapt to. What some would call "excessive" force used to free up someone's locktite-laden regret isn't even enough to scuff the finish on this little guy. If you often work, or see yourself working on a number of ARs in the future, this wrench is well worth the investment. The areas to fit your torque wrench are sized correctly (you do have a 1/2" drive torque wrench, right?). If you need a wrench, get it. Is it more expensive? Yeah. It's also better than every single one out there.
