    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.

    Great Wrench! I bought it for my taper mount flash hiders, I like it better than you general wrench because of the way smaller size to not make it real awkward when tightening your muzzle device. Thanks Griffin!

    Great to keep in the Range Bag

    Can't count how many times this tool has came in handy on the range and in the garage. The thin profile is great for installing muzzle devices and castle nuts. BONUS POINTS for the adult beverage opener!!!!
