Although it's expensive, the wrench is very well made and nice and heavy. The finish does not rub off easy either. Last wrench I will probably ever buy!

Awesome, best I've used.
Magpul AR Wrench

Excellent product as expected, heavy duty forged construction and finish to last a lifetime. Used it to get off a particularly stuck barrel nut that took more than my body weight to break loose. Awesome tool, buy one over a cheaper wrench and you won't be disappointed.
What a tool!
For quite some time had been unhappy with the selection of wimpy AR15-related wrenches and tools in my toolbox. When I received the Primary Arms e-mail with the sale pricing on the Magpul AR-15 Armorers Wrench, I had to pull the trigger. This is a substantial tool that, at first glance, had what appeared to have too many options to be useful. I was wrong. This is a well-engineered piece of gear that is just the right length to provide great leverage. The finish is grippy, even with oily hands. The actual working parts of the tool are well-machined fit perfectly for the wide variety of purposes it was designed for. I would not trade this tool for any reason. I have since not hesitated to recommend it to anyone who would listen.
Great wrench, glad I finally found it!
For some reason I have not been able to find one of these in stores or at other websites. Primary arms was the only place that had it and I'm glad I made the purchase. This wrench made building my latest AR as well as tearing down an old one for Cerakote a breeze. 100% satisfied with the wrench and Primary Arms

Best wrench I have used
by Bill A
I thought that this was very expensive for an AR wrench but once you see it and use it you will think it's well worth the extra cost. It's solid - well made and not coated w a think layer of paint the usually needs to be filed down on the contact surfaces so they fit. Torque opening is for 1/2" torque wrench. A quality well thought out wrench
Sturdy tool, lacks what others have though
by M Davis
It isn't able to screw a muzzle break on and off which is annoying, but it does work great for barrel nut and buffer tube installation.
rock solid tool
by Matt Sproul
much better than my tapco
Magpul just does everything better!
No this is not a cheap wrench, but Primary Arms sales puts it less than $60. Did I have to have it or spend that much... No, but I now have the last wrench I'll ever need & if times get tight, no problem finding a buyer! The weight alone is proof that this isn't the one time build cheap wrench to never be used again. I was raised to use the right tool for the right job & Magpul is that right tool!!!
Great quality, heavy
Really like this wrench.

There are AR wrenches out there that have more features, but this one is REALLY well built

There are better tools to use in the shop, but this works fine in a pinch in the field.

Great Product, Great Price, Fast Shipping, Thanks
One poster says it won't tighten a muzzle brake
It will screw in a standard ar15 muzzle break. You use the slot in the same end that is for the castle nut!
Doesn't work with Aero Precision BAR nut
Used for a new build and was surprised to find that wrench does not work with Aero Precision BAR barrel nut. The AP nut has only 4 holes and the Magpul wrench has 7 pins. The other functions of the wrench (flash hider, castle nut, bottle opener) work well though.
but watch out for scratches!This wrench is very sturdy and works well; however I have found you have to be very careful using it or it will scratch up your buffer tube buffer tube nut etc. If it wasn't so deadly on the finish of my rifle parts I'd give it five stars easy.
I purchased a $20 AR wrench off of eBay for my first build. I honestly just didn't know better. That crap wrench's barrel nut lugs bent on the first AR I built and it was then completely unusable for any future builds. I needed a new wrench after a friend an I decided to convert our ARs to .300BLK. I was highly recommended this wrench by my got to gunsmith. I haven't used it yet but it did come in the other day and I can say that from fit to finish this is an excellent and sturdy tool and a highly welcomed tool in my AR tool box. I have zero doubts that this wrench will by far out perform the prior wrench I owned.
Best Wrench Ever!
Hey I'm sure I'm just like a lot of you? Bought a cheap wrench and hated the results. First thing I noticed was the weight of it. It's not overtly heavy but it's built to last. Solid piece I'm glad I spent the extra money to get a product that's not going to tear up the finish on my rifles nor will it tear up the nut while trying to remove it. The fit is perfect on every part of the tool. I'd buy it again! And definatly I'd recommend it to anyone who owns an AR or variant there of. And it's been hard coat anodized! Also has the Torque amounts for the Castle ring barrel nut and muzzle device stamped into the handle! Very nice! Worked like a charm with my personal torque wrench. I couldn't of asked for a better wrench.
functional tool.This tools is very well-built. I considered cheaper options but I'm glad I went ahead and got this one. Primary Arms got it shipped to me very quickly.
useful tool!This tool is a bit pricey but you do get what you pay for. It is heavy duty and well made. I think it will be around for a long while.
