    Dependable multi-function Armorer's wrench

    Posted by William Foshee on 11th May 2022

    This is a quality product from Magpul. It gives you the ability to remove or install castle nuts, barrel nuts and muzzle devices. There are cheaper Armorer's wrenches out there, but this one is solid and built to last. It also lists the torque specs for castle nuts, barrel nuts and muzzle devices on the wrench. One of the most important features is the square cutout for your torque wrench, so you know you are using the correct amount of torque.

    Great wrench with one drawback.

    Posted by David on 17th Mar 2022

    The wrench is very well made and gets 5 stars for quality. I took a star off because the wrench did not fit my Spikes Tactical BAR2 barrel nut. It is made for the more commen type of nuts and will not fit all. But other than at it’s a excellent product.

    Best Wrench

    Posted by Jon on 31st Jan 2022

    This is the best wrench I own. I have several wrenches that I got for cheap and they work okay, but this one works a lot better, especially for castle nuts.
