    Absolute BEST AR wrench out there. Bonus of being for both AR15 and AR10 builds.Add a breaker bar, or torque wrench to this and you’ll never use any other [AR] wrench. Extremely glad that I bought this wrench instead of any of the other ones available. Or even the sets of wrenches (sets of two to get the same job done). With the barrel nut pins going all the way through the wrench, there’s no weak point in it. I’ve used this to build, or help build, several AR15’s now. Both in 5.56/.223 and 300 Blackout. With this wrench, it’s sofa king easy.

    This is an amazing wrench!!!! You really cannot find a more solid, well-built AR15/AR10 combo wrench out there. Solid construction, not overly heavy and super solid all around. I highly recommend this wrench at anyone that plans on building an AR15 or AR10!!

    I recently purchased this wrench and am using it. I could not be more pleased with the workmanship put into this fine piece of engineering. All wrench openings fit precisely yet easily. Wrench openings are well laid out. Edges are crisp without being sharp. There is nothing crude about this tool. Yet it has the feel and and appearance of massive strength. It’s clearly made and finished with care. I’m glad I found it.

    I have the combo wrench- it’s an outstanding tool. I’ve used it for several builds / revisions to AR’s and it’s still as good as new. Very heavy construction and tough, hard pins hold up to heavy use. I can’t imagine a better tool for AR’s, in fact this is one of my favorite specialty tools for any purpose.

    I was waiting on another company to make more of their wrenches but still haven’t heard back from them. So one night i found this wrench and ordered one,had great communication with this company and the wrench shipped fast. Used this wrench on my ar and everything on the wrench worked great. Its a nice solid made tool.

    It got a tough staked castle nut off of a colt lower buffer tube. I placed the lower minus the stock down on the carpet with the label/stamp facing up, and then applied pressure on mag-well with my knee. This allowed me the leverage to push down with the AR tool correctly seated in the castle nut to break it free. I wrapped the buffer tube with several wraps of aluminum tape to prevent nicks and scrathes. Also penetrating oil left overnight to soak into the castle nut is a good idea. This idea was courtesy of a user off of, and it worked for me. Results may vary if your castle nut was attached with locktite.

    I was doing some research on what wrench to buy when i came across the link for and decided to give them a look. So glad i did. THis thing is built like a tank. Even a buddy of mine who was an armorer in the Air Force for 20 years commented on how nice it was Needless to say I love this thing. Customer service is second to none and shipping was super fast. Can’t wait for until next build. Great job Weaponwerx. I will be checking in often for new products. keep up the great work.

    I have the combo wrench and used it for my .308AR and AR-15 builds.

    This is a stout, well-engineered piece. Very high quality. Precision-machined, it fits everything it’s supposed to and does what you need an armorer’s wrench to do.

    If anything ever breaks on my guns this thing would make a fine defensive weapon in its own right.

    Buy with confidence.

    I consult AR-15 and AR-10 builds. I had been eyeballing a Magpul wrench because I love pretty much everything they make. However, after seeing this wrench I had to give the nod to weaponwerx. Good quality steel, and has everything I need in one tool. Not a flimsy design at all like so many of the other products you’ll see floating around. Nice, solid, well machined tool. Highly suggest you get one.

    Bought this wrench about a year ago and I am certain it will be the last one I buy. Unlike most others it does it’s job. No teeth gritting nor wrench spreading and skinned knuckles, barrels or barrel nuts. Not cheap but worth every dime. What is a proper wrench worth to you?

    I received the combo wrench a couple days ago and already finished a rifle with it. This is by far the best one I’ve ever used, far superior to the other ones I’ve used before. I’m very happy with every aspect of this purchase experience, extremely fast shipping, great product and finally a fantastic price! Thanks weapon werx!

    Got the wrench today, looks great! Fit was excellent on my nut and flash hider, there were no marks after I snugged it down good! You have a well made, beautiful, and quality product, I’ll be keeping it in the safe too! It is much underrated! You should do some other tools! Thank-you again for a fine tool!

    Weaponwerx’s combo ar15/ar10 wrench is a much better design and cheaper than Magpul’s. It’s open ended rather than closed like the Magpul’s design which requires you to remove your stock/brace before accessing the castle nut. Also the Weaponwerx works on both AR15 and DPMS/AR10 barrel nuts. Better designed, cheaper, and made in the US. Go ahead and smash that BUY button.
