    Irritated that I had to buy a third armorers wrench, I was looking to find an inexpensive wrench for timing my muzzle break. I needed a thin wrench and this one met my needs. It’s quality made and the right price. Thanks guys.

    This is a quality tool. Especially considering the price. Griffin also goes the extra mile and packages it nicely. You can tell when a company takes some pride in their work and it shows in this tool.

    Wrench worked awesome and is thin to work muzzle devices and spacers. The tool is a little rough manufacturing only reason i didnt give it 5 stars

    Was looking for tool to tighten and time the Dead Air Keymo Muzzle Brake to an MPX-K ILWT threaded barrel in conjunction with my Torque Wrench 1/2" Drive. Worked out amazingly. Excellent craftsmanship and multipurpose. Very satisfied!

    Good fitment on gun parts. Needed this to get between shims and muzzle brake. Can't beat the price for this tool.

    Perfect for torque-ing a muzzle device

    Published by M. Humphrey on 10th Jun 2020

    I needed something to install a muzzle device to be used with a suppressor. I had a number of tools for installing the muzzle device, but none to which I could both attach a torque wrench, and that also didn't have pins or some other obstruction that would get in the way. This tool was perfect for the task.

    I was very pleased to find this wrench. It works perfectly For my need. It is very difficult to find a thin wrench to fit between the limited space of my rail and muzzle device.
