Does anyone make a skinny wrench for installing a 5/8x24 muzzle device without hitting the shims? Pic attached. Best if it will interface with a 1/2" square drive for a torque wrench.

| I used a well-used Snap-On tappet wrench I scored off Ebay for like 10 bucks for a long time. The FCD wrench is excellent as well. I have one and I use it all the time. It fits the flats without slop and doesn't round the corners off on the muzzle device flats. |

I have a set of husky slim wrenches. Sold at the local home depot. https://www.homedepot.com/pep/Husky-Thin-Head-Access-Wrench-Set-6-Piece-H6PCTWS/314256097 I also have a set of gliffin muzzle device wrenches. They are less complete than an actual wrench set and less immediately available. |

Shims should be much thinner and not much greater than the width of the barrel. They definitely shouldn't prevent a normal 1/2-inch wrench from fitting.
