    Best Armorer's Wrench Available

    Posted by B. Hawkins on 10th Jan 2017

    I have used a number of different armorer's wrenches on AR15 builds over the years, and this Magpul version is my favorite by far. It fits very well on castle nuts, etc and feels solid in the hand. One end houses the barrel nut wrench and other end contains the castle nut wrench, and both ends seem to have less chance for slippage than other versions previously used. It costs more than many other similar wrenches out there, but if you use it more than a few times you will find it to be well worth the price.
