Top Choice

The AR armorer's wrench is a compact tool holding over 10 tools that serve over a dozen functions. The wrench contains a small hammer head, an A2 buffer-tube socket, and a 3/4-inch wrench for muzzle devices. A barrel nut wrench works with both encapsulated and pin-style barrel nuts, including the GI-style nut. A castle-nut driver has a three-notch engagement system, and the drive end of the wrench works for all MI free-float barrel nuts with included fittings for the CRM, CRLW, CRT, G3M, G4M, SLH, SP, and ULW series nuts. The wrench also has a two-inch drive socket for a torque wrench with torque spec features stamped right on the wrench handle. Midwest Industries didn't forget anything and even added a combat bottle opener.

Superior Craftsmanship

The professional armorer's wrench is made from 4140 heat-treated steel and given a flat black finish. It weighs just over 16 ounces and measures just over one-foot long.

Easy to Use

The AR armorer's wrench is an all-in-one, easy-to-use tool that contains virtually all the tools you need to make field adjustments to your AR 5.56 and/or 7.62 caliber platforms.
