AR-15 Armorer's Wrench

Mark W.
Out of spec

Out of spec. The castle nut part works but the section for removing d-ring nut was off by about 2mm. Rounded off the teeth making it impossible to salvage

Tool broke, not worth it to return.

The teeth used to grab the caslte nut sheared off rendering the tool useless. I thought maybe China can at least heat treat a tool but nope.


Much better than the one have been using . This one is great and strong. Did not cam out during torqueing barrel nut.

Pretty good armorer's wrench

I recently did my first build with a Rainer select barrel on a Standard mil-spec receiver with a Aero Precision hand guard. The Aero Precision barrel nut is a royal pain to find the correct wrench for. I returned two before keeping this one. I had to file down two of the pins until they were in the correct location to torque the barrel nut. The pins were in the right place, just a little mis-aligned. The wrench worked just fine after filing. And the Castle nut side also works fine. I haven't put on a muzzle compensator yet, but there are lots of standard wrenches that can do that job so I probably wouldn't use this wrench for that job anyway. It's a good wrench. Not a great wrench, but it was only $25.00.
