tried a $15 one first to tighten my castle nut. it was terrible, so i bought this one and it worked perfectly. i left a negative review on the junk one but it hasn't been added to reviews for some reason. don't make my mistake, just buy this one. also shipping was amazingly fast as always.
Best wrench ever

I got a cheap castle nut multi wrench when I first started building. After getting one of these, now its the first tool I grab for. Never had an issue using this bad boy. Got about 6 builds in and it's still going strong. Heavy duty solid construction.
Every AR builder needs one of these

I’ll never buy any other brand of armorers wrench again. This is the best quality AR wrench I’ve ever had by far!! The quality of the tool surpasses anything else I’ve ever used on my builds. No more castle wrench slips.
just get it already

So beautiful, not sure if i'm just gonna hang it on the wall. solid wrench. magpul will replace if you break it.
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.
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.
A must for AR builds!

We install parts for our customers we build and service AR15/10 everyday and we use and abuse this Magpul wrench daily! We got away from those terrible "multi-wrench-junk" years ago and invested in specific gun smith tools specific to AR15"...but that meant our range bag got pretty heavy. I had a issue one day and didn't have my castle nut wrench and a fellow shooter handed me this wrench...I said to myself "this castle nut will never be the same". To my surprise it was an awesome wrench. In my opinion the best thing Magpul has every put out! Now all my guys have one and we love them!
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.
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.
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.

great customer survive
by O K
There are AR wrenches out there that have more features, but this one is REALLY well built
Great quality, heavy
Really like this wrench.
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!!!
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

rock solid tool
by Matt Sproul
much better than my tapco
by Conrado Galan
I always need a Armorers wrench, work smarter not harder.
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!
by Timothy Nelson
There are better tools to use in the shop, but this works fine in a pinch in the field.
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.
