Magpul Armorer’s Wrench and BEV Block

I know a lot of you have been waiting for these. Magpul officially released their Armorer’s Wrench and BEV Block today.


Magpul Armorer’s Wrench

It is amazing to me how few top quality AR-15 armorer’s wrenches there are on the market. The majority of them are junk and I have seen several that didn’t make it through a single build. Magpul’s introduction of their Amorer’s Wrench is important because it is well designed, I expect that it will be very well made, and Magpul has the resources to distribute it widely (which is an issue with many of the better wrenches available now).

Here is what Magpul has to say about their wrench:

The Magpul Armorer’s Wrench: Requirement Driven, Purpose Built

The Magpul Armorer’s Wrench is an exceptional product in a number of ways; its design, construction, and intent are a level above what has traditionally been available in a dedicated AR15 assembly and maintenance tool. However, one of the most unique things about the Armorer’s Wrench is the product development process that brought it to market. The Armorer’s Wrench was actually a product requested for Magpul’s internal use and then developed into a commercial product.

At Magpul, our diverse and ever-expanding product line necessitates a tremendous amount of testing. Some of these tests include tolerance of environmental conditions, chemical and UV resistance, and controlled scientific strength testing among many others. As to be expected, one extremely crucial part of our product validation prior to bringing a new item to market is high-volume live fire testing. We are fortunate to have a wide selection of high-quality firearms and access to great industry partners and suppliers to maintain these firing schedules, and the world-class armorers at Magpul stay very busy repairing, refitting, reconfiguring, and maintaining our armory.

The Armorer’s Wrench was purpose designed and built to provide our armory with a tool that would stand up to the volume of use that other tools could not sustain, as well as providing optimized functionality for the tasks it had to perform. The cost and lost time of breaking tools at an unacceptable rate came led to our armorers asking the company to apply our proven design and manufacturing expertise to solving their problem, and the Magpul Armorer’s Wrench is the result. While the cost was slightly higher than some other armorer’s tools, the function and durability more than offset the cost difference. Once the wrench proved its worth in our shop, the Armorer’s Wrench transitioned to a production item with a singular goal made possible by its many functions: to provide the professional, institutional, or recreational armorer the finest commercially available AR15-pattern tool ever produced.


American-Made, solid steel construction with grip-enhancing phosphate finish engages both Mil-Spec and pin-style barrel nuts. Fits standard sized flash hiders. Installs and removes rifle receiver extensions and carbine castle nuts, with extended teeth for use with ASAP plates. Two hammer faces. Works with 1/2” torque wrench, relevant torque specifications included on Wrench for quick reference. Convenient Bottle Opener for refreshments after the build is complete (fits both Metric and SAE bottle caps.)


BEV Block

The BEV Block is just a clever, clever tool. It just makes sense to secure the barrel at the lugs, rather than the upper, when doing certain common tasks like installing flash suppressors or torquing a barrel nut.


The BEV Block (Barrel Extension Vise) is an all-in-one, compact vise block tool for AR assembly operations of barrel nuts, flash hiders, etc. Mounts securely in a vise and provides support for both billet and forged upper and lower receivers. Engages barrel extension with solid steel lugs and full length support shank to prevent flexing. Steel hardness is optimized for durability yet won’t damage barrel extension, and Magpul Polymer for all other engagement surfaces to protect aluminum receiver. O-ring post uses bolt carrier for additional stability and included Pin keeps upper in proper position.

You can check out both the Armorer’s Wrench and BEV Block on Magpul’s website. Both tools are part of their Armorer’s Tool Series. Hopefully that means there are more tools to come.

    It makes sense to hold the upper by the barrel when working on the barrel.
    However, I’m confused why you would want to hold the upper by the barrel while screwing a nut onto the upper. Doesn’t that put all of the torque on the barrel indexing pin?
