Model Number: AR Armorer’s Wrench
Color: Pewter
Material: Carbon Steel

KEY DIFFERENCES BETWEEN THE TWO WRENCHES::

Wrench B: The 3 pins on Wrench B are slightly smaller in diameter than those on Wrench A, allowing them to fit perfectly into the holes of the barrel nut on the quad rail handguard and the 1.8 ID handguard. It is also suitable for installing the MK18 handguard.
Wrench A: Wrench A offers more functionality, but if used with the three handguards mentioned above, some sanding will be required.

Ehhh

This thing didn’t really work that great. The dimensions didn’t fit the castle nut, or muzzle devices. I didn’t bother trying it on anything else after that.

ohhunt® AR15 Armorer's Barrel Nut Castle Nut Wrench for M4 M16 Multi-Fuction Tool

Not made for heavy work

I bought this Armorer’s Wrench to do change out hand guards meaning I needed to unscrew the barrel nut from the previous hand guard and then **** and tighten the new barrel nut. The wrench is not as well built as other Armorer’s Wrenches that I own. On trying to unscrew the previous barrel nut with the pin wrench portion, the pin sheared off and no other portion of the wrench fit. I did get the previous barrel nut off and used the Ohhunt wrench to tighten the new barrel nut on for the Ohhunt hand guard which uses the 3 pin circular wrench portion. I did have to profit the pins to the barrel nut because a painted? cover on the pins would not allow them to enter the holes. Overall, not a quality wrench. Maybe I got what I paid for.

You get what you pay for.

Honestly the worst armorer's wrench I own, but also the cheapest. Decent for loaning to a friend who needs one. The one strong selling point is it has a decent finish on it, which is nice compared to some of the options

Poor quality

Item broke on first use and it has been a hassle to get a refund. Company is trying to say it is user fault instead of admitting the product quality is poor.

Doesn't work with my OhHunt forend.

I checked, as per OhHunt's recommendation. They indicate that the fit is too sloppy to work without damaging the barrel nut. They do suggest an alternate wrench but have no idea where to find it.
The upper vise block won't fit my Aero upper either. A complete bust.

Great wrench!

Had a cheapie wrench before that wouldn't stay on the castle nut. Got this one at a good price - love it. Nice grip on the handle and a lot better balance for torqueing.

Great upper receiver vice block

I bought the upper receiver vice block and when I received it I opened the bag it was in and took it out to look at it. When I separated the two halfs something fell out and I found it on the floor. When I looked at the block halfs I noticed that one side had two holes and the other side had one locating pin on closer inspection I saw a divot that matched the part that fell out. I glued the part back to where it belonged where it stayed until I used it to hold the upper receiver while I torqued the barrel nut holding the barrel to the receiver. It worked like it was supposed to even though a locating pin broke off in shipping which is not a big concern for me because I will drill a hole and install a new pin solving the issue. I am happy to have this new tool that works great and was affordable because the local stores wanted four times the price that I paid for it for the same thing.

Armorers combo wrench tool and upper receiver vise block

Received the items in good time and in good condition. I was impressed that it took longer to unpack the items from the packaging than to torque the barrel on my AR. Good addition to my shop at a good price,

Tool great, worried about block

Tool appears to both functional and strong, but slightly worried about the block and its longevity. Great price for what I got though.
